Check Digit Verification of cas no
The CAS Registry Mumber 138506-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,0 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138506-39:
(8*1)+(7*3)+(6*8)+(5*5)+(4*0)+(3*6)+(2*3)+(1*9)=135
135 % 10 = 5
So 138506-39-5 is a valid CAS Registry Number.
