Check Digit Verification of cas no
The CAS Registry Mumber 12217-97-9 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 12217-97:
(7*1)+(6*2)+(5*2)+(4*1)+(3*7)+(2*9)+(1*7)=79
79 % 10 = 9
So 12217-97-9 is a valid CAS Registry Number.
