121133-33-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121133-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121133-33:
(8*1)+(7*2)+(6*1)+(5*1)+(4*3)+(3*3)+(2*3)+(1*3)=63
63 % 10 = 3
So 121133-33-3 is a valid CAS Registry Number.
