1330573-33-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1330573-33-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,0,5,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1330573-33:
(9*1)+(8*3)+(7*3)+(6*0)+(5*5)+(4*7)+(3*3)+(2*3)+(1*3)=125
125 % 10 = 5
So 1330573-33-5 is a valid CAS Registry Number.
