Check Digit Verification of cas no
The CAS Registry Mumber 742017-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,2,0,1 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 742017-20:
(8*7)+(7*4)+(6*2)+(5*0)+(4*1)+(3*7)+(2*2)+(1*0)=125
125 % 10 = 5
So 742017-20-5 is a valid CAS Registry Number.
