53566-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53566-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,5,6 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 53566-46:
(7*5)+(6*3)+(5*5)+(4*6)+(3*6)+(2*4)+(1*6)=134
134 % 10 = 4
So 53566-46-4 is a valid CAS Registry Number.

Xia, Yi,Fanqi, Qu,Wei, Li,Qiongyou, Wu,Peng, Ling
, p. 345 - 352 (2005)
Bitriazolyl compounds were synthesized via Huisgen 1,3-cyclcoaddition starting with an azidotriazole and various alkynes. Good yields were obtained with terminal alkynes using copper(I) as a catalyst in the THF/H2O system.
