Check Digit Verification of cas no
The CAS Registry Mumber 161146-82-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,1,4 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161146-82:
(8*1)+(7*6)+(6*1)+(5*1)+(4*4)+(3*6)+(2*8)+(1*2)=113
113 % 10 = 3
So 161146-82-3 is a valid CAS Registry Number.
