Check Digit Verification of cas no
The CAS Registry Mumber 137368-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,6 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137368-83:
(8*1)+(7*3)+(6*7)+(5*3)+(4*6)+(3*8)+(2*8)+(1*3)=153
153 % 10 = 3
So 137368-83-3 is a valid CAS Registry Number.

Pyrido annelation reaction by a tandem aza Wittig/electrocyclic ring-closure strategy: Preparation of pyrazolo[4,3-c]- and pyrazolo[3,4-c]pyridine derivatives
Molina,Aller,Lorenzo
, p. 6737 - 6746 (2007/10/02)
The aza Wittig-type reaction of iminophosphorane 3, prepared from 5-formyl-1-phenylpyrazole by sequential treatment with ethyl azidoacetate and triphenylphosphine, with isocyanates, ketenes, aldehydes and carbon disulfide leads to the functionalized pyrazolo[4,3-c]pyridines 5, 7, 9 and 11 respectively. Iminophosphorane 15, prepared from 4-formyl-1-phenylpyrazole, undergoes pyrido annelation by reaction with ketenes to give the isomeric pyrazolo[3,4-c]pyridines 22 in modest yields.
