39887-72-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39887-72-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 39887-72:
(7*3)+(6*9)+(5*8)+(4*8)+(3*7)+(2*7)+(1*2)=184
184 % 10 = 4
So 39887-72-4 is a valid CAS Registry Number.
