349141-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 349141-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,9,1,4 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 349141-17:
(8*3)+(7*4)+(6*9)+(5*1)+(4*4)+(3*1)+(2*1)+(1*7)=139
139 % 10 = 9
So 349141-17-9 is a valid CAS Registry Number.
