Check Digit Verification of cas no

The CAS Registry Mumber 189829-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,2 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189829-34:
(8*1)+(7*8)+(6*9)+(5*8)+(4*2)+(3*9)+(2*3)+(1*4)=203
203 % 10 = 3
So 189829-34-3 is a valid CAS Registry Number.

An unusual solvent effect on the regiochemical outcome (N-9 versus N-7) of guanine glycosylation using Robins' reagent (2-N-acetyl-6-O- diphenylcarbamoylguanine)

Cheung, Adrian Wai-Hing,Sidduri, Achyutharao,Garofalo, Lisa M.,Goodnow Jr., Robert A.

, p. 3303 - 3307 (2000)

An unexpectedly low N-9/N-7 regioselectivity was obtained when Robins reagent (2-N-acetyl-6-O-diphenylcarbamoylguanine) was coupled with a D- glucosamine derivative under trimethylsilyl trifluoromethanesulfonate activation. An unprecedented solvent effect (toluene versus dichloroethane) on the N-9/N-7 ratio was also observed in the same study. The use of 2-N- acetyl-6-O-benzylguanine to successfully overcome the above regioselectivity problem is described. (C) 2000 Elsevier Science Ltd.
