Check Digit Verification of cas no
The CAS Registry Mumber 23322-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23322-64:
(7*2)+(6*3)+(5*3)+(4*2)+(3*2)+(2*6)+(1*4)=77
77 % 10 = 7
So 23322-64-7 is a valid CAS Registry Number.
