Check Digit Verification of cas no
The CAS Registry Mumber 138904-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,0 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138904-35:
(8*1)+(7*3)+(6*8)+(5*9)+(4*0)+(3*4)+(2*3)+(1*5)=145
145 % 10 = 5
So 138904-35-5 is a valid CAS Registry Number.
