Check Digit Verification of cas no
The CAS Registry Mumber 66193-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,9 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66193-63:
(7*6)+(6*6)+(5*1)+(4*9)+(3*3)+(2*6)+(1*3)=143
143 % 10 = 3
So 66193-63-3 is a valid CAS Registry Number.
