Check Digit Verification of cas no
The CAS Registry Mumber 105941-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,4 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105941-35:
(8*1)+(7*0)+(6*5)+(5*9)+(4*4)+(3*1)+(2*3)+(1*5)=113
113 % 10 = 3
So 105941-35-3 is a valid CAS Registry Number.

, p. 562 - 565 (2007/10/02)
4-Chlorosulfonyl-α-naphthylchalcone (2) has been prepared and characterised as the sulfonamides (3-7).With N,N-dimethylhydrazine, 2 gives the chalconedimethylhydrazide (8); reaction with hydrazine and N-methylhydrazine affords the pyrazolines (9, 17) and
