Check Digit Verification of cas no
The CAS Registry Mumber 6638-93-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6638-93:
(6*6)+(5*6)+(4*3)+(3*8)+(2*9)+(1*3)=123
123 % 10 = 3
So 6638-93-3 is a valid CAS Registry Number.
