Check Digit Verification of cas no
The CAS Registry Mumber 25317-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,1 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 25317-39:
(7*2)+(6*5)+(5*3)+(4*1)+(3*7)+(2*3)+(1*9)=99
99 % 10 = 9
So 25317-39-9 is a valid CAS Registry Number.
