Check Digit Verification of cas no
The CAS Registry Mumber 136491-14-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,9 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136491-14:
(8*1)+(7*3)+(6*6)+(5*4)+(4*9)+(3*1)+(2*1)+(1*4)=130
130 % 10 = 0
So 136491-14-0 is a valid CAS Registry Number.

A novel synthesis of 3,4-disubstituted-1H-pyrazolo[3,4-b]quinolines
Narsaiah,Sivaprasad,Venkataratnam
, p. 1611 - 1617 (2007/10/02)
A simple and efficient synthesis of pyrazolo[3,4-b]quinolines is described. The synthesis involves reaction of 2-amino-3-cyanoquinoline-4-carboxylates (1) with hydrazine hydrate to give regioselectively only pyrazolo[3,4-b]quinolines (2). No formation of
