934562-64-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 934562-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,5,6 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 934562-64:
(8*9)+(7*3)+(6*4)+(5*5)+(4*6)+(3*2)+(2*6)+(1*4)=188
188 % 10 = 8
So 934562-64-8 is a valid CAS Registry Number.

A new protecting group and linker for uridine ureido nitrogen

Wang, Yong,Kurosu, Michio

scheme or table, p. 4797 - 4804 (2012/08/08)

(2,6-Dichloro-4-methoxyphenyl)(2,4,6-trichlorophenyl) methoxymethyl chloride [1, monomethoxydiph-enylmethoxylmethyl chloroide (MDPM-Cl)] shows a significant relative stability and 1 reacts with uridine ureido nitrogen in the presence of DBU to form the corresponding protected uridine 8 in 95% yield. The MDPM-protected uridines are stable to a wide variety of conditions utilized for the synthesis of analogs of capuramycin and muraymycins. Significantly, the MDPM protecting group can conveniently be deprotected by using 30% TFA in CH 2Cl2. In addition, polymer-bound MDPM-Cl 23 is useful for immobilization of uridine derivatives.

High-throughput synthesis of substituted hydrazine derivatives

Kurosu, Michio,Narayanasamy, Prabagaran,Crick, Dean C.

scheme or table, p. 169 - 175 (2009/09/08)

Regioselective alkylations of the hydrazine derivatives are achieved by using the (2,6-dichloro-4-methoxyphenyl)(2,4-dichlorophenyl)methoxycarboxyl resin. High-throughput synthesis of monosubstituted and 1,1-disubstituted hydrazine building blocks is desc
