149405-17-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149405-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,0 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149405-17:
(8*1)+(7*4)+(6*9)+(5*4)+(4*0)+(3*5)+(2*1)+(1*7)=134
134 % 10 = 4
So 149405-17-4 is a valid CAS Registry Number.
