Check Digit Verification of cas no
The CAS Registry Mumber 304660-64-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,6,6 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 304660-64:
(8*3)+(7*0)+(6*4)+(5*6)+(4*6)+(3*0)+(2*6)+(1*4)=118
118 % 10 = 8
So 304660-64-8 is a valid CAS Registry Number.
