1338565-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338565-58-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,6 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1338565-58:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*6)+(3*5)+(2*5)+(1*8)=184
184 % 10 = 4
So 1338565-58-4 is a valid CAS Registry Number.

A convergent strategy for the synthesis of polycyclic ethers by using oxiranyl anions
Sakai, Takeo,Sugimoto, Ai,Mori, Yuji
, p. 5850 - 5853 (2012/01/19)
A new [X+2+Y]-type for the convergent synthesis of polycyclic ethers based on an oxiranyl anion strategy was developed. The sequence involves nucleophilic substitution of a triflate with an oxiranyl anion followed by 6-endo cyclization, ring expansion, an
