Check Digit Verification of cas no
The CAS Registry Mumber 4702-64-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4702-64:
(6*4)+(5*7)+(4*0)+(3*2)+(2*6)+(1*4)=81
81 % 10 = 1
So 4702-64-1 is a valid CAS Registry Number.
