81252-30-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81252-30-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,5 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81252-30:
(7*8)+(6*1)+(5*2)+(4*5)+(3*2)+(2*3)+(1*0)=104
104 % 10 = 4
So 81252-30-4 is a valid CAS Registry Number.

Analogs of pyrimidine nucleosides. 16. Racemic 2′,3′-dideoxynucleosides and their derivatives

Kaulinya,Liepin'sh,Lidak,Zhuk

, p. 85 - 93 (2007/10/02)

The chlorination of 2-halomethyltetrahydrofurans and acyl derivatives of tetrahydrofuryl alcohol wasstudied; mixtures of 2,5- and 2,2-disubstituted tetrahydrofurans are formed as a result of the reaction. 2,4-Bis(trimethylsilyl) derivatives of uracil, 5-substituted uracils, and cytosine are alkylated by the resulting mixtures of α-chloro ethers without separation, and mixtures of cis and transisomers of 1-(5-substituted-2-tetrahydrofuryl) and 1-(2-substituted-2-tetrahydrofuryl) derivatives of uracil, 5-substituted uracils, and cytosine are obtained. The reaction products were identified onthe basis of their PMR spectra.
