144852-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144852-11-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,5 and 2 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144852-11:
(8*1)+(7*4)+(6*4)+(5*8)+(4*5)+(3*2)+(2*1)+(1*1)=129
129 % 10 = 9
So 144852-11-9 is a valid CAS Registry Number.
