172656-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172656-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,5 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172656-99:
(8*1)+(7*7)+(6*2)+(5*6)+(4*5)+(3*6)+(2*9)+(1*9)=164
164 % 10 = 4
So 172656-99-4 is a valid CAS Registry Number.
