133407-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133407-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,0 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133407-53:
(8*1)+(7*3)+(6*3)+(5*4)+(4*0)+(3*7)+(2*5)+(1*3)=101
101 % 10 = 1
So 133407-53-1 is a valid CAS Registry Number.
