Check Digit Verification of cas no
The CAS Registry Mumber 73957-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,5 and 7 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73957-66:
(7*7)+(6*3)+(5*9)+(4*5)+(3*7)+(2*6)+(1*6)=171
171 % 10 = 1
So 73957-66-1 is a valid CAS Registry Number.
