132533-48-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132533-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,5,3 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132533-48:
(8*1)+(7*3)+(6*2)+(5*5)+(4*3)+(3*3)+(2*4)+(1*8)=103
103 % 10 = 3
So 132533-48-3 is a valid CAS Registry Number.
