1333238-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1333238-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,3 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1333238-52:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*3)+(3*8)+(2*5)+(1*2)=130
130 % 10 = 0
So 1333238-52-0 is a valid CAS Registry Number.
