Check Digit Verification of cas no

The CAS Registry Mumber 89817-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,1 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89817-99:
(7*8)+(6*9)+(5*8)+(4*1)+(3*7)+(2*9)+(1*9)=202
202 % 10 = 2
So 89817-99-2 is a valid CAS Registry Number.

Pyridinethiones. VIII. The Aldol and Wittig Condensations of 3-Formyl-2(1H)-pyridones, -thiones and -selenones. Preparation of New Cyanopyridones

Michael, Maged Aziz,Becher, Jan,Winckelmann, Ib

, p. 1651 - 1656 (2007/10/02)

Condensations of 1-substituted-3-formyl-2(1H)-pyridones, -thiones and -selenones with methyl ketones such as acetophenone give the corresponding chalcones in high yields.Geometry at the vinyl hydrogens is E.These chalcones can be cyclized with ethyl cyano
