Check Digit Verification of cas no
The CAS Registry Mumber 163808-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,8,0 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163808-81:
(8*1)+(7*6)+(6*3)+(5*8)+(4*0)+(3*8)+(2*8)+(1*1)=149
149 % 10 = 9
So 163808-81-9 is a valid CAS Registry Number.
