189822-79-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189822-79-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,8,2 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189822-79:
(8*1)+(7*8)+(6*9)+(5*8)+(4*2)+(3*2)+(2*7)+(1*9)=195
195 % 10 = 5
So 189822-79-5 is a valid CAS Registry Number.

On the use of removable steric buttresses in cycloaddition reactions
Choony, Nandeo,Dadabhoy, Anjum,Sammes, Peter G.
, p. 2017 - 2021 (2007/10/03)
Use of bulky protecting groups, such as the trityl group, can be utilised to encourage cycloaddition reactions that otherwise do not proceed. Thus N-allylfurfurylamines, bearing the appropriate N-protecting group, can thermally cyclise; subsequent removal
