Check Digit Verification of cas no

The CAS Registry Mumber 95491-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,4,9 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 95491-09:
(7*9)+(6*5)+(5*4)+(4*9)+(3*1)+(2*0)+(1*9)=161
161 % 10 = 1
So 95491-09-1 is a valid CAS Registry Number.

Carbonylbiscaprolactam: A Versatile Reagent for Organic Synthesis and Isocyanate-Free Urethane Chemistry

Maier, Steffen,Loontjens, Ton,Scholtens, Boudewijn,Muelhaupt, Rolf

, p. 5094 - 5097 (2007/10/03)

The power of the rings: The reactions of carbonylbiscaprolactam (CBC, 1) with amines and alcohols proceed either by ring elimination (RE) or by ring opening (RO). The conversion and selectivity of these reactions were optimized in studies with various hydroxy and amino compounds, catalysts, reaction temperatures, and ratios of 1/nucleophile.
