Check Digit Verification of cas no

The CAS Registry Mumber 189633-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189633-70:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*3)+(2*7)+(1*0)=183
183 % 10 = 3
So 189633-70-3 is a valid CAS Registry Number.

, p. 5813 - 5824 (2007/10/03)

Partial hydrolysis of the nitrile moiety in aeetylated 1-bromo-glycopyranosyl cyanides 1 and 9 mediated by TiCl4 gave C-(1-bromo-1-deoxy-glycopyranosyl) formamides 2 and 10 whose reaction either with AgOCN, AgSCN or KSCN in nitromethane resulted in the formation of glycopyranosylidene-spirohydantoins 3, 11 and 15 and -thiohydantoins 7 and 16. Zemplen-deacetylation gave the pyranoid epihydantocidin analogues 4 and 12, and thiohydantocidin analogues 8 and 17, respectively.
