Check Digit Verification of cas no
The CAS Registry Mumber 144432-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,3 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144432-85:
(8*1)+(7*4)+(6*4)+(5*4)+(4*3)+(3*2)+(2*8)+(1*5)=119
119 % 10 = 9
So 144432-85-9 is a valid CAS Registry Number.
