83004-37-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83004-37-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,0 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83004-37:
(7*8)+(6*3)+(5*0)+(4*0)+(3*4)+(2*3)+(1*7)=99
99 % 10 = 9
So 83004-37-9 is a valid CAS Registry Number.
