Check Digit Verification of cas no

The CAS Registry Mumber 187242-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,4 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 187242-28:
(8*1)+(7*8)+(6*7)+(5*2)+(4*4)+(3*2)+(2*2)+(1*8)=150
150 % 10 = 0
So 187242-28-0 is a valid CAS Registry Number.

Synthesis and Some Transformations of 5-Benzotriazolyl-3,4-dihydropyrid-2-ones

Katritzky, Alan R.,Shcherbakova, Irina V.

, p. 2031 - 2036 (1996)

5-(Benzotriazolyl)-substituted 3,4-dihydropyrid-2-ones were obtained by condensation of 4-benzotriazolyl-5-phenyl(methyl)-5-oxopentanoic acids with benzyl or aryl amines. Dehydrogenation of 3,4-dihydropyrid-2-ones resulted in 5-benzotriazolyl-substituted pyrid-2-ones and/or 5-(phenyl-amino)pyrid-2-ones, products of nitrogen elimination from the benzotriazolyl substituent. In turn, 5-benzotriazol-1-yl-substituted pyrid-2-ones eliminated nitrogen under Graebe-Ullmann conditions to give indolopyridones.
