89110-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89110-42-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,1 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89110-42:
(7*8)+(6*9)+(5*1)+(4*1)+(3*0)+(2*4)+(1*2)=129
129 % 10 = 9
So 89110-42-9 is a valid CAS Registry Number.
