Check Digit Verification of cas no

The CAS Registry Mumber 192568-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,5,6 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 192568-43:
(8*1)+(7*9)+(6*2)+(5*5)+(4*6)+(3*8)+(2*4)+(1*3)=167
167 % 10 = 7
So 192568-43-7 is a valid CAS Registry Number.

Reaction of 4-oxochromene-3-carboxaldehydes with primary amides and benzotriazole or 1H-1,2,4-triazole

Stankovicova, Henrieta,Gasparova, Renata,Lacova, Margita,Chovancova, Jarmila

, p. 781 - 790 (1997)

N-[(6-substituted-4-oxochromen-3-yl)(1,2,4-triazol-3-yl)methyl]amides 5 and N-[(6-substituted-4-oxochromen-3-yl)(benzotriazol-1-yl)methyl]amides 6 were prepared by the reaction of 6-substituted 4-oxochromene-3-carboxaldehydes 1 with primary amides and 1H-1,2,4-triazole or 1H-benzotriazole. 6-Substituted 3-[hydroxy(1,2,4-triazol-1-yl)methyl]chromen-4-one 2 and 6-substituted 3-[hydroxy-(benzotriazol-1-yl)methyl]chromen-4-one 3 were isolated as stable intermediates of these reactions. Beneficial effect of microwave irradiation on length of reaction time was observed. Some reactions of these derivatives with O, S, and N nucleophiles are described.
