Check Digit Verification of cas no
The CAS Registry Mumber 145397-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,9 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145397-22:
(8*1)+(7*4)+(6*5)+(5*3)+(4*9)+(3*7)+(2*2)+(1*2)=144
144 % 10 = 4
So 145397-22-4 is a valid CAS Registry Number.
