115951-98-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 115951-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,9,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115951-98:
(8*1)+(7*1)+(6*5)+(5*9)+(4*5)+(3*1)+(2*9)+(1*8)=139
139 % 10 = 9
So 115951-98-9 is a valid CAS Registry Number.
