133993-43-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133993-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,9 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 133993-43:
(8*1)+(7*3)+(6*3)+(5*9)+(4*9)+(3*3)+(2*4)+(1*3)=148
148 % 10 = 8
So 133993-43-8 is a valid CAS Registry Number.
