Check Digit Verification of cas no
The CAS Registry Mumber 462116-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,2,1,1 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 462116-78:
(8*4)+(7*6)+(6*2)+(5*1)+(4*1)+(3*6)+(2*7)+(1*8)=135
135 % 10 = 5
So 462116-78-5 is a valid CAS Registry Number.
