Check Digit Verification of cas no
The CAS Registry Mumber 140647-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,4 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140647-73:
(8*1)+(7*4)+(6*0)+(5*6)+(4*4)+(3*7)+(2*7)+(1*3)=120
120 % 10 = 0
So 140647-73-0 is a valid CAS Registry Number.
