Check Digit Verification of cas no
The CAS Registry Mumber 145300-99-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,0 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145300-99:
(8*1)+(7*4)+(6*5)+(5*3)+(4*0)+(3*0)+(2*9)+(1*9)=108
108 % 10 = 8
So 145300-99-8 is a valid CAS Registry Number.
