4119-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4119-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,1 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4119-09:
(6*4)+(5*1)+(4*1)+(3*9)+(2*0)+(1*9)=69
69 % 10 = 9
So 4119-09-9 is a valid CAS Registry Number.
