81033-23-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81033-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,3 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81033-23:
(7*8)+(6*1)+(5*0)+(4*3)+(3*3)+(2*2)+(1*3)=90
90 % 10 = 0
So 81033-23-0 is a valid CAS Registry Number.
