18239-19-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18239-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18239-19:
(7*1)+(6*8)+(5*2)+(4*3)+(3*9)+(2*1)+(1*9)=115
115 % 10 = 5
So 18239-19-5 is a valid CAS Registry Number.
