Check Digit Verification of cas no

The CAS Registry Mumber 72666-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,6 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72666-49:
(7*7)+(6*2)+(5*6)+(4*6)+(3*6)+(2*4)+(1*9)=150
150 % 10 = 0
So 72666-49-0 is a valid CAS Registry Number.

Synthesis of Some New 2,4,6-Triarylpyridines Using Phenacylpyridinium Ylid

Malik, Saroj,Tewari, R. S.,Srivastava, N.,Nigam, R. K.,Gupta, K. C.

, p. 242 - 243 (2007/10/02)

Phenacylpyridinium ylid reacts with some substituted benzylidene-2-acetothiophenes, benzylidene-4-chloroacetophenones and benzylidene-3-nitroacetophenones in the presence of ammonium acetate in methanol or glacial acetic acid to give 2-phenyl-4-substituted-phenyl-6-(2-thienyl)pyridines (5a-e), 2-phenyl-4-substituted-phenyl-6-(4-chlorophenyl)pyridines (5f-j) and 2-phenyl-4-substituted-phenyl-6-(3-nitrophenyl)pyridines (5k-m), respectively in fair to good yields.
