41869-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 41869-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,6 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 41869-91:
(7*4)+(6*1)+(5*8)+(4*6)+(3*9)+(2*9)+(1*1)=144
144 % 10 = 4
So 41869-91-4 is a valid CAS Registry Number.
