923557-20-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 923557-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,5,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 923557-20:
(8*9)+(7*2)+(6*3)+(5*5)+(4*5)+(3*7)+(2*2)+(1*0)=174
174 % 10 = 4
So 923557-20-4 is a valid CAS Registry Number.
