154333-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154333-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,3,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 154333-33:
(8*1)+(7*5)+(6*4)+(5*3)+(4*3)+(3*3)+(2*3)+(1*3)=112
112 % 10 = 2
So 154333-33-2 is a valid CAS Registry Number.
