Check Digit Verification of cas no

The CAS Registry Mumber 91515-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91515-91:
(7*9)+(6*1)+(5*5)+(4*1)+(3*5)+(2*9)+(1*1)=132
132 % 10 = 2
So 91515-91-2 is a valid CAS Registry Number.

Imidazolyl Derivatives of The Chroman Ring. 1.

Cozzi, Paolo,Mongelli, Nicola,Pillan, Antonio

, p. 311 - 315 (2007/10/02)

The synthesis of 2-(1H-imidazol-1-yl)-2,3-dihydro-2H-1-benzopyran-4-ones (I) through 3-bromo-2,3-dihydro-4H-1-benzopyran-4-ones or more conveniently through chroman ring closure from 2-(1H-imidazol-1-yl)-2'-hydroxy-acetophenones is described.The ring closure also works well for the pyrazolyl derivatives.Compounds I and the corresponding imidazolylchromanols, -chromenes, and -chromans derived from the former, were pharmacologically investigated.
