133533-72-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133533-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,3 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133533-72:
(8*1)+(7*3)+(6*3)+(5*5)+(4*3)+(3*3)+(2*7)+(1*2)=109
109 % 10 = 9
So 133533-72-9 is a valid CAS Registry Number.
