Check Digit Verification of cas no
The CAS Registry Mumber 627060-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,7,0,6 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 627060-62:
(8*6)+(7*2)+(6*7)+(5*0)+(4*6)+(3*0)+(2*6)+(1*2)=142
142 % 10 = 2
So 627060-62-2 is a valid CAS Registry Number.

Synthesis of 3,4-diamino-1H-pyrazolo[3,4-d]pyrimidines
Tumkyavichyus
, p. 716 - 720 (1996)
The reaction of 4-(amino-substituted)-2-methylthio-6-chloropyrimidine-5-carbonitriles with hydrazine and methylhydrazine was used to synthesize 3,4-diamino-6-methylthio-1H-pyrazolo[3,4-d]pyrimidines. It was shown that the formation of pyrazolopyrimidines
