Check Digit Verification of cas no

The CAS Registry Mumber 941670-58-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,1,6,7 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 941670-58:
(8*9)+(7*4)+(6*1)+(5*6)+(4*7)+(3*0)+(2*5)+(1*8)=182
182 % 10 = 2
So 941670-58-2 is a valid CAS Registry Number.

2H-Pyrazol-3-ylamines as precursors for the synthesis of polyfunctionally substituted pyrazolo[1,5-a]pyrimidines

Anwar, Hany Fakhry,Fleita, Daisy Hanna,Kolshorn, Heinz,Meier, Herbert,Elnagdi, Mohamed Hilmy

, p. 133 - 141 (2013/09/12)

Substituted aminopyrazoles (5a-d) were synthesized and reacted with bidentate electrophiles to afford pyrazolo[1,5-a]pyrimidines. The regioorientation of reagents has been determined by (15N, 1H) HMBC measurements as well as an X-ray crystal structure determination. ARKAT.
