Check Digit Verification of cas no
The CAS Registry Mumber 2947-64-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2947-64:
(6*2)+(5*9)+(4*4)+(3*7)+(2*6)+(1*4)=110
110 % 10 = 0
So 2947-64-0 is a valid CAS Registry Number.
