119043-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119043-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,0,4 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119043-20:
(8*1)+(7*1)+(6*9)+(5*0)+(4*4)+(3*3)+(2*2)+(1*0)=98
98 % 10 = 8
So 119043-20-8 is a valid CAS Registry Number.
