Check Digit Verification of cas no

The CAS Registry Mumber 1380215-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,2,1 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1380215-13:
(9*1)+(8*3)+(7*8)+(6*0)+(5*2)+(4*1)+(3*5)+(2*1)+(1*3)=123
123 % 10 = 3
So 1380215-13-3 is a valid CAS Registry Number.

Microwave-assisted synthesis of fused pyrazolo[3,4-b]pyrazines by the reaction of ortho-aminonitrosopyrazoles and cyclic β-diketones

Quiroga, Jairo,Sánchez, Norha E.,Acosta, Paola,Insuasty, Braulio,Abonia, Rodrigo

experimental part, p. 3181 - 3187 (2012/07/31)

Novel fused pyrazolo[3,4-b]pyrazines 3 were prepared by assisted microwave cyclocondensation reaction of ortho-aminonitrosopyrazoles 1 and cyclic β-diketones 2 in dimethylformamide. This protocol provides a simple procedure for the synthesis of the title compounds with the advantages of easy work-up, mild reaction conditions and good yields.
