144732-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144732-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,3 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144732-30:
(8*1)+(7*4)+(6*4)+(5*7)+(4*3)+(3*2)+(2*3)+(1*0)=119
119 % 10 = 9
So 144732-30-9 is a valid CAS Registry Number.
