Check Digit Verification of cas no
The CAS Registry Mumber 667940-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,9,4 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 667940-71:
(8*6)+(7*6)+(6*7)+(5*9)+(4*4)+(3*0)+(2*7)+(1*1)=208
208 % 10 = 8
So 667940-71-8 is a valid CAS Registry Number.
