Check Digit Verification of cas no
The CAS Registry Mumber 140157-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,5 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140157-01:
(8*1)+(7*4)+(6*0)+(5*1)+(4*5)+(3*7)+(2*0)+(1*1)=83
83 % 10 = 3
So 140157-01-3 is a valid CAS Registry Number.
