Check Digit Verification of cas no

The CAS Registry Mumber 67818-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,1 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67818-00:
(7*6)+(6*7)+(5*8)+(4*1)+(3*8)+(2*0)+(1*0)=152
152 % 10 = 2
So 67818-00-2 is a valid CAS Registry Number.

Addition of 4-Phenyltriazolinedione to Carbonyl Compounds: The Formation of α-Urazolylcarbonyl Compounds

Wilson, R. Marshall,Hengge, Alvan C.,Ataei, Ali,Chantarasiri, Nuanphun

, p. 193 - 197 (2007/10/02)

N-Phenyltriazolinedione (PTAD) adds to a variety of carbonyl compounds to form α-urazolylcarbonyl compounds.With highly enolized carbonyl systems, this type of substitution reaction can occur rapidly even in the absence of a catalyst.However, with simple
