486998-57-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 486998-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,6,9,9 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 486998-57:
(8*4)+(7*8)+(6*6)+(5*9)+(4*9)+(3*8)+(2*5)+(1*7)=246
246 % 10 = 6
So 486998-57-6 is a valid CAS Registry Number.
