Check Digit Verification of cas no
The CAS Registry Mumber 720672-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,0,6,7 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 720672-40:
(8*7)+(7*2)+(6*0)+(5*6)+(4*7)+(3*2)+(2*4)+(1*0)=142
142 % 10 = 2
So 720672-40-2 is a valid CAS Registry Number.
