Check Digit Verification of cas no
The CAS Registry Mumber 120217-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,1 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120217-40:
(8*1)+(7*2)+(6*0)+(5*2)+(4*1)+(3*7)+(2*4)+(1*0)=65
65 % 10 = 5
So 120217-40-5 is a valid CAS Registry Number.
