69518-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69518-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,5,1 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 69518-18:
(7*6)+(6*9)+(5*5)+(4*1)+(3*8)+(2*1)+(1*8)=159
159 % 10 = 9
So 69518-18-9 is a valid CAS Registry Number.
