Check Digit Verification of cas no
The CAS Registry Mumber 667402-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,4,0 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 667402-65:
(8*6)+(7*6)+(6*7)+(5*4)+(4*0)+(3*2)+(2*6)+(1*5)=175
175 % 10 = 5
So 667402-65-5 is a valid CAS Registry Number.
