26910-35-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26910-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,1 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26910-35:
(7*2)+(6*6)+(5*9)+(4*1)+(3*0)+(2*3)+(1*5)=110
110 % 10 = 0
So 26910-35-0 is a valid CAS Registry Number.
