Check Digit Verification of cas no
The CAS Registry Mumber 766515-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,6,5,1 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 766515-35:
(8*7)+(7*6)+(6*6)+(5*5)+(4*1)+(3*5)+(2*3)+(1*5)=189
189 % 10 = 9
So 766515-35-9 is a valid CAS Registry Number.

Synthesis of 3,5-difunctionalized 1-methyl-1H-pyrazolo[3,4-b]pyridines involving palladium-mediated coupling reactions
Lavecchia,Berteina-Raboin,Guillaumet
, p. 6633 - 6636 (2004)
Indirect iodination of 2-chloro-nicotinonitrile gave 2-chloro-5- iodonicotinonitrile, which was cyclized with methylhydrazine to lead to 3-amino-5-iodopyrazolo[3,4-b]pyridine. Position 3 was then protected by pivaloyl group and the resulting 5-iodo-3-pivaloylaminopyrazolo[3,4-b]pyridine was engaged in palladium-promoted coupling reactions with various reagents to give 3-pivaloylamino-5-substituted compounds. Deprotection and iododediazoniation followed by cross-coupling reactions in position 3 afforded novel unsymmetrical 3,5-disubstituted pyrazolo[3,4-b]pyridine species.
