107291-10-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107291-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,2,9 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 107291-10:
(8*1)+(7*0)+(6*7)+(5*2)+(4*9)+(3*1)+(2*1)+(1*0)=101
101 % 10 = 1
So 107291-10-1 is a valid CAS Registry Number.
