Check Digit Verification of cas no
The CAS Registry Mumber 816464-90-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,6,4,6 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 816464-90:
(8*8)+(7*1)+(6*6)+(5*4)+(4*6)+(3*4)+(2*9)+(1*0)=181
181 % 10 = 1
So 816464-90-1 is a valid CAS Registry Number.

Dzvinchuk,Turov,Lozinskii
, p. 798 - 802 (2006)
A convenient method is proposed for the synthesis of the previously unknown 4-aryl-1,3-diphenyl-1,4,5,10-tetrahydropyrazolo[3,4-b][1,5]benzodiazepines by cyclocondensation of 5-(2-aminoanilino)-1,3-diphenylpyrazole with aromatic aldehydes. The reaction on
