Check Digit Verification of cas no
The CAS Registry Mumber 12217-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,1 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12217-95:
(7*1)+(6*2)+(5*2)+(4*1)+(3*7)+(2*9)+(1*5)=77
77 % 10 = 7
So 12217-95-7 is a valid CAS Registry Number.
