Check Digit Verification of cas no
The CAS Registry Mumber 443-93-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 443-93:
(5*4)+(4*4)+(3*3)+(2*9)+(1*3)=66
66 % 10 = 6
So 443-93-6 is a valid CAS Registry Number.
