144841-87-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144841-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,4 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144841-87:
(8*1)+(7*4)+(6*4)+(5*8)+(4*4)+(3*1)+(2*8)+(1*7)=142
142 % 10 = 2
So 144841-87-2 is a valid CAS Registry Number.
