Check Digit Verification of cas no
The CAS Registry Mumber 17233-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,3 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17233-65:
(7*1)+(6*7)+(5*2)+(4*3)+(3*3)+(2*6)+(1*5)=97
97 % 10 = 7
So 17233-65-7 is a valid CAS Registry Number.
