Check Digit Verification of cas no
The CAS Registry Mumber 144817-80-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,1 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144817-80:
(8*1)+(7*4)+(6*4)+(5*8)+(4*1)+(3*7)+(2*8)+(1*0)=141
141 % 10 = 1
So 144817-80-1 is a valid CAS Registry Number.
