890306-83-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 890306-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,3,0 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 890306-83:
(8*8)+(7*9)+(6*0)+(5*3)+(4*0)+(3*6)+(2*8)+(1*3)=179
179 % 10 = 9
So 890306-83-9 is a valid CAS Registry Number.
