194724-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194724-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,7,2 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 194724-17:
(8*1)+(7*9)+(6*4)+(5*7)+(4*2)+(3*4)+(2*1)+(1*7)=159
159 % 10 = 9
So 194724-17-9 is a valid CAS Registry Number.
