Check Digit Verification of cas no
The CAS Registry Mumber 16403-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,0 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 16403-84:
(7*1)+(6*6)+(5*4)+(4*0)+(3*3)+(2*8)+(1*4)=92
92 % 10 = 2
So 16403-84-2 is a valid CAS Registry Number.
