Check Digit Verification of cas no
The CAS Registry Mumber 146398-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,3,9 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 146398-94:
(8*1)+(7*4)+(6*6)+(5*3)+(4*9)+(3*8)+(2*9)+(1*4)=169
169 % 10 = 9
So 146398-94-9 is a valid CAS Registry Number.
