Check Digit Verification of cas no
The CAS Registry Mumber 85138-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,3 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85138-49:
(7*8)+(6*5)+(5*1)+(4*3)+(3*8)+(2*4)+(1*9)=144
144 % 10 = 4
So 85138-49-4 is a valid CAS Registry Number.
