91233-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91233-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,3 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91233-25:
(7*9)+(6*1)+(5*2)+(4*3)+(3*3)+(2*2)+(1*5)=109
109 % 10 = 9
So 91233-25-9 is a valid CAS Registry Number.
