Check Digit Verification of cas no
The CAS Registry Mumber 116-75-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 116-75:
(5*1)+(4*1)+(3*6)+(2*7)+(1*5)=46
46 % 10 = 6
So 116-75-6 is a valid CAS Registry Number.
