82109-99-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82109-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82109-99:
(7*8)+(6*2)+(5*1)+(4*0)+(3*9)+(2*9)+(1*9)=127
127 % 10 = 7
So 82109-99-7 is a valid CAS Registry Number.
