Check Digit Verification of cas no
The CAS Registry Mumber 68583-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,8 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 68583-95:
(7*6)+(6*8)+(5*5)+(4*8)+(3*3)+(2*9)+(1*5)=179
179 % 10 = 9
So 68583-95-9 is a valid CAS Registry Number.
