144633-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144633-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,3 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144633-19:
(8*1)+(7*4)+(6*4)+(5*6)+(4*3)+(3*3)+(2*1)+(1*9)=122
122 % 10 = 2
So 144633-19-2 is a valid CAS Registry Number.

Generation and cycloaddition reactions of transient alkyl-substituted anhydro-4-hydroxythiazolium hydroxides
Hertzog, Donald L.,Nadler, William R.,Zhang, Zhijia J.,Padwa, Albert
, p. 5877 - 5880 (1992)
Transient alkyl-substituted anhydro-4-hydroxythiazolium hydroxides undergo efficient inter- and intramolecular cycloaddition to provide the corresponding 1,3-dipolar cycloadducts in high yield.
