174497-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 174497-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,4,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 174497-93:
(8*1)+(7*7)+(6*4)+(5*4)+(4*9)+(3*7)+(2*9)+(1*3)=179
179 % 10 = 9
So 174497-93-9 is a valid CAS Registry Number.
