Check Digit Verification of cas no
The CAS Registry Mumber 185422-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,4,2 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 185422-82:
(8*1)+(7*8)+(6*5)+(5*4)+(4*2)+(3*2)+(2*8)+(1*2)=146
146 % 10 = 6
So 185422-82-6 is a valid CAS Registry Number.
