Check Digit Verification of cas no
The CAS Registry Mumber 113894-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,8,9 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113894-38:
(8*1)+(7*1)+(6*3)+(5*8)+(4*9)+(3*4)+(2*3)+(1*8)=135
135 % 10 = 5
So 113894-38-5 is a valid CAS Registry Number.
