18542-37-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18542-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,5,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18542-37:
(7*1)+(6*8)+(5*5)+(4*4)+(3*2)+(2*3)+(1*7)=115
115 % 10 = 5
So 18542-37-5 is a valid CAS Registry Number.
