Check Digit Verification of cas no
The CAS Registry Mumber 144223-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,2 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144223-32:
(8*1)+(7*4)+(6*4)+(5*2)+(4*2)+(3*3)+(2*3)+(1*2)=95
95 % 10 = 5
So 144223-32-5 is a valid CAS Registry Number.
