Check Digit Verification of cas no
The CAS Registry Mumber 68399-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68399-71:
(7*6)+(6*8)+(5*3)+(4*9)+(3*9)+(2*7)+(1*1)=183
183 % 10 = 3
So 68399-71-3 is a valid CAS Registry Number.
