112233-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112233-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,2,3 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112233-51:
(8*1)+(7*1)+(6*2)+(5*2)+(4*3)+(3*3)+(2*5)+(1*1)=69
69 % 10 = 9
So 112233-51-9 is a valid CAS Registry Number.
