89311-41-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89311-41-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,1 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89311-41:
(7*8)+(6*9)+(5*3)+(4*1)+(3*1)+(2*4)+(1*1)=141
141 % 10 = 1
So 89311-41-1 is a valid CAS Registry Number.
