119995-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119995-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,9 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 119995-16:
(8*1)+(7*1)+(6*9)+(5*9)+(4*9)+(3*5)+(2*1)+(1*6)=173
173 % 10 = 3
So 119995-16-3 is a valid CAS Registry Number.
