Check Digit Verification of cas no
The CAS Registry Mumber 134716-82-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,1 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134716-82:
(8*1)+(7*3)+(6*4)+(5*7)+(4*1)+(3*6)+(2*8)+(1*2)=128
128 % 10 = 8
So 134716-82-8 is a valid CAS Registry Number.
