Check Digit Verification of cas no
The CAS Registry Mumber 119968-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,9,6 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119968-51:
(8*1)+(7*1)+(6*9)+(5*9)+(4*6)+(3*8)+(2*5)+(1*1)=173
173 % 10 = 3
So 119968-51-3 is a valid CAS Registry Number.
