Check Digit Verification of cas no

The CAS Registry Mumber 158119-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,1,1 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 158119-60:
(8*1)+(7*5)+(6*8)+(5*1)+(4*1)+(3*9)+(2*6)+(1*0)=139
139 % 10 = 9
So 158119-60-9 is a valid CAS Registry Number.

Modified Bucherer-Bergs reaction for the one-pot synthesis of 5,5′-disubstituted hydantoins from nitriles and organometallic reagents

Montagne, Cyril,Shipman, Michael

, p. 2203 - 2206 (2007/10/03)

Diverse sets of 5,5′-disubstituted hydantoins can conveniently be made in moderate to good yields (40-92%) by a one-pot process involving treatment of aromatic, heteroaromatic or aliphatic nitriles with an organometallic reagent (RLi or RMgX) followed by
