Check Digit Verification of cas no
The CAS Registry Mumber 120034-73-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,3 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120034-73:
(8*1)+(7*2)+(6*0)+(5*0)+(4*3)+(3*4)+(2*7)+(1*3)=63
63 % 10 = 3
So 120034-73-3 is a valid CAS Registry Number.
