Check Digit Verification of cas no
The CAS Registry Mumber 21461-86-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,6 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21461-86:
(7*2)+(6*1)+(5*4)+(4*6)+(3*1)+(2*8)+(1*6)=89
89 % 10 = 9
So 21461-86-9 is a valid CAS Registry Number.
