Check Digit Verification of cas no
The CAS Registry Mumber 64611-73-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,1 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 64611-73:
(7*6)+(6*4)+(5*6)+(4*1)+(3*1)+(2*7)+(1*3)=120
120 % 10 = 0
So 64611-73-0 is a valid CAS Registry Number.
