Check Digit Verification of cas no
The CAS Registry Mumber 68138-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,3 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68138-99:
(7*6)+(6*8)+(5*1)+(4*3)+(3*8)+(2*9)+(1*9)=158
158 % 10 = 8
So 68138-99-8 is a valid CAS Registry Number.
