Check Digit Verification of cas no

The CAS Registry Mumber 87276-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,7 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87276-33:
(7*8)+(6*7)+(5*2)+(4*7)+(3*6)+(2*3)+(1*3)=163
163 % 10 = 3
So 87276-33-3 is a valid CAS Registry Number.

A NOVEL SYNTHESIS OF THE CYCLIC CARBINOLAMIDE MOIETY OF THE MAYTANSINOIDS

Petrakis, Konstantinos S.,Fried, Josef

, p. 3065 - 3066 (2007/10/02)

The α-diketo-urethane 3 cyclizes to form the cyclic carbinolamide 4 using TMS triflate and 2,6-di-t-butylpyridine.The siloxy group of 4 is readily exchanged in methanol or water to form 6 or 7.Remarkably, 3 does not cyclize spontaneously or on standard acid catalysis.
