Check Digit Verification of cas no
The CAS Registry Mumber 285137-96-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,5,1,3 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 285137-96:
(8*2)+(7*8)+(6*5)+(5*1)+(4*3)+(3*7)+(2*9)+(1*6)=164
164 % 10 = 4
So 285137-96-4 is a valid CAS Registry Number.
