Calculate Digit Verification of CAS Registry Number 1630974-69:
(9*1)+(8*6)+(7*3)+(6*0)+(5*9)+(4*7)+(3*4)+(2*6)+(1*9)=184
184 % 10 = 4
So 1630974-69-4 is a valid CAS Registry Number.

Facile one-pot synthesis of 1,3,5-trisubstituted pyrazoles from α,β-enones

Yu, Jin,Kim, Ko Hoon,Moon, Hye Ran,Kim, Jae Nyoung

, p. 1692 - 1696 (2014/07/07)

A practical and efficient one-pot synthesis of 1,3,5-trisubstituted pyrazoles from α,β-enones and arylhydrazine hydrochlorides has been developed. The pyrazoles were formed via a tandem formation of the corresponding pyrazolines and an acid-catalyzed aerobic oxidation process.
