119090-39-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119090-39-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,9 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119090-39:
(8*1)+(7*1)+(6*9)+(5*0)+(4*9)+(3*0)+(2*3)+(1*9)=120
120 % 10 = 0
So 119090-39-0 is a valid CAS Registry Number.
