143869-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143869-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,6 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143869-49:
(8*1)+(7*4)+(6*3)+(5*8)+(4*6)+(3*9)+(2*4)+(1*9)=162
162 % 10 = 2
So 143869-49-2 is a valid CAS Registry Number.
