Check Digit Verification of cas no
The CAS Registry Mumber 12270-76-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,7 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12270-76:
(7*1)+(6*2)+(5*2)+(4*7)+(3*0)+(2*7)+(1*6)=77
77 % 10 = 7
So 12270-76-7 is a valid CAS Registry Number.
