50-88-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50-88-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 0 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 50-88:
(4*5)+(3*0)+(2*8)+(1*8)=44
44 % 10 = 4
So 50-88-4 is a valid CAS Registry Number.

An Improved Approach for Practical Synthesis of 5-Hydroxymethyl-2′-deoxycytidine (5hmdC) Phosphoramidite and Triphosphate

Chen, Zhen-Zhen,Chi, Mei,Dong, Ying-Ying,Pu, Shou-Zhi,Sun, Qi,Yang, Dong-Zhao

, (2022/01/31)

5-Hydroxymethyl-2′-deoxycytidine (5hmdC) phosphoramidite and triphosphate are important building blocks in 5hmdC-containing DNA synthesis for epigenetic studies. However, efficient and practical methods for the synthesis of these compounds are

SYNTHESIS AND IMPROVEMENT OF A NUCLEOSIDE ANALOGUE AS AN ANTI-CANCER AND ANTI-VIRAL DRUG

-

Page/Page column 7; 13, (2021/05/29)

The invention is a drug for anticancer and antiviral therapy, comprising a nucleoside analogue (7) comprising a furan ring irreversibly bound to the RNA/DNA synthesis chain by phosphodiester bonds and having SP3 hybridization, and folic acid (A) bound to the nucleoside analogue (7) comprising furan ring. The synthesis method of the said nucleoside analogue is also contained within the scope of the invention. In this work, a nucleoside-analogue was transformed after converting the furan-ring hybridization from Sp2 to Sp3 to make it more selectivity with different enzymes and linking it via site 5 with the effective folic acid towards entering the substances inside the cells and to become the final compound possessing anti-cancer and anti- virus properties after controlling the replication and reproduction process in DNA.

Meteorite-catalyzed intermoleculartrans-glycosylation produces nucleosides under proton beam irradiation

Bizzarri, Bruno Mattia,Fanelli, Angelica,Kapralov, Michail,Krasavin, Eugene,Saladino, Raffaele

, p. 19258 - 19264 (2021/06/03)

Di-glycosylated adenines act as glycosyl donors in the intermoleculartrans-glycosylation of pyrimidine nucleobases under proton beam irradiation conditions. Formamide and chondrite meteorite NWA 1465 increased the yield and the selectivity of the reaction
