Check Digit Verification of cas no
The CAS Registry Mumber 57968-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,6 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 57968-81:
(7*5)+(6*7)+(5*9)+(4*6)+(3*8)+(2*8)+(1*1)=187
187 % 10 = 7
So 57968-81-7 is a valid CAS Registry Number.
