Check Digit Verification of cas no
The CAS Registry Mumber 52831-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52831-99:
(7*5)+(6*2)+(5*8)+(4*3)+(3*1)+(2*9)+(1*9)=129
129 % 10 = 9
So 52831-99-9 is a valid CAS Registry Number.
