119909-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119909-50-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,0 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119909-50:
(8*1)+(7*1)+(6*9)+(5*9)+(4*0)+(3*9)+(2*5)+(1*0)=151
151 % 10 = 1
So 119909-50-1 is a valid CAS Registry Number.
