Check Digit Verification of cas no

The CAS Registry Mumber 54249-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,2,4 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 54249-00:
(7*5)+(6*4)+(5*2)+(4*4)+(3*9)+(2*0)+(1*0)=112
112 % 10 = 2
So 54249-00-2 is a valid CAS Registry Number.

Synthesis of 1H-[1]Benzothieno[3.2-c]pyrazoles

Sauter,Bueyuek,Jordis

, p. 869 - 876 (2007/10/07)

Derivatives of 1 H-[1]Benzothieno[3,2-c]pyrazole were synthesized by a new method: 1.3-dipolar cycloaddition of substituted benzo[b]thiophene-1.1-dioxides with C-methyl-N-phenyl and C,N-diaryl-nitrilimines, resp., gave the corresponding title compounds. The structure was proved by conversion to known compounds.
