Check Digit Verification of cas no
The CAS Registry Mumber 73653-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,5 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73653-80:
(7*7)+(6*3)+(5*6)+(4*5)+(3*3)+(2*8)+(1*0)=142
142 % 10 = 2
So 73653-80-2 is a valid CAS Registry Number.
