89091-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89091-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,9 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89091-53:
(7*8)+(6*9)+(5*0)+(4*9)+(3*1)+(2*5)+(1*3)=162
162 % 10 = 2
So 89091-53-2 is a valid CAS Registry Number.
