Check Digit Verification of cas no
The CAS Registry Mumber 608-89-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.Calculate Digit Verification of CAS Registry Number 608-89:
(5*6)+(4*0)+(3*8)+(2*8)+(1*9)=79
79 % 10 = 9
So 608-89-9 is a valid CAS Registry Number.
