133993-38-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133993-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,9 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133993-38:
(8*1)+(7*3)+(6*3)+(5*9)+(4*9)+(3*3)+(2*3)+(1*8)=151
151 % 10 = 1
So 133993-38-1 is a valid CAS Registry Number.
