535993-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 535993-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,5,9,9 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 535993-23:
(8*5)+(7*3)+(6*5)+(5*9)+(4*9)+(3*3)+(2*2)+(1*3)=188
188 % 10 = 8
So 535993-23-8 is a valid CAS Registry Number.
