Check Digit Verification of cas no
The CAS Registry Mumber 58131-66-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,1,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58131-66:
(7*5)+(6*8)+(5*1)+(4*3)+(3*1)+(2*6)+(1*6)=121
121 % 10 = 1
So 58131-66-1 is a valid CAS Registry Number.
