4496-92-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4496-92-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,9 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4496-92:
(6*4)+(5*4)+(4*9)+(3*6)+(2*9)+(1*2)=118
118 % 10 = 8
So 4496-92-8 is a valid CAS Registry Number.
