133493-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133493-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133493-40:
(8*1)+(7*3)+(6*3)+(5*4)+(4*9)+(3*3)+(2*4)+(1*0)=120
120 % 10 = 0
So 133493-40-0 is a valid CAS Registry Number.
