Check Digit Verification of cas no

The CAS Registry Mumber 173347-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,4 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 173347-43:
(8*1)+(7*7)+(6*3)+(5*3)+(4*4)+(3*7)+(2*4)+(1*3)=138
138 % 10 = 8
So 173347-43-8 is a valid CAS Registry Number.

SYNTHESIS OF N-(ω-TRIMETHYLSILYLALKYL)PURINES UNDER CONDITIONS OF INTERFACIAL CATALYSIS

Alksnis, E.,Lidak, M.,Kyjevits, E.

, p. 577 - 581 (1995)

A method of synthesis of N-(ω-trimethylsilylalkyl)purines, by alkylation of potassium salts of purine bases by 3-chloropropyltrimethylsilane and chloromethyltrimethylsilanes under conditions of interfacial catalysis, has been developed.Hydroxylation of the N-allyl group by dimethylphenylsilane, which is an alternative pathway of synthesis of silicon-containing purine derivatives, has been accomplished for the first time in the purine series.The structure of the compounds obtained was established by methods of PMR and UV spectroscopy.
