Check Digit Verification of cas no
The CAS Registry Mumber 16980-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,8 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16980-40:
(7*1)+(6*6)+(5*9)+(4*8)+(3*0)+(2*4)+(1*0)=128
128 % 10 = 8
So 16980-40-8 is a valid CAS Registry Number.
