105962-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105962-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,6 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105962-64:
(8*1)+(7*0)+(6*5)+(5*9)+(4*6)+(3*2)+(2*6)+(1*4)=129
129 % 10 = 9
So 105962-64-9 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
