Check Digit Verification of cas no
The CAS Registry Mumber 146173-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,1,7 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 146173-77:
(8*1)+(7*4)+(6*6)+(5*1)+(4*7)+(3*3)+(2*7)+(1*7)=135
135 % 10 = 5
So 146173-77-5 is a valid CAS Registry Number.
