18593-69-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18593-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,9 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18593-69:
(7*1)+(6*8)+(5*5)+(4*9)+(3*3)+(2*6)+(1*9)=146
146 % 10 = 6
So 18593-69-6 is a valid CAS Registry Number.
