5629-08-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5629-08-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,2 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5629-08:
(6*5)+(5*6)+(4*2)+(3*9)+(2*0)+(1*8)=103
103 % 10 = 3
So 5629-08-3 is a valid CAS Registry Number.
