923289-10-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 923289-10-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,2,8 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 923289-10:
(8*9)+(7*2)+(6*3)+(5*2)+(4*8)+(3*9)+(2*1)+(1*0)=175
175 % 10 = 5
So 923289-10-5 is a valid CAS Registry Number.
