Check Digit Verification of cas no
The CAS Registry Mumber 2163-80-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2163-80:
(6*2)+(5*1)+(4*6)+(3*3)+(2*8)+(1*0)=66
66 % 10 = 6
So 2163-80-6 is a valid CAS Registry Number.
