74581-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74581-35-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,8 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74581-35:
(7*7)+(6*4)+(5*5)+(4*8)+(3*1)+(2*3)+(1*5)=144
144 % 10 = 4
So 74581-35-4 is a valid CAS Registry Number.

REGIOSELECTIVE AND CONNECTIVE ROUTES TO OXETANES AND TETRAHYDROFURANES
Sevrin, M.,Krief, A.
, p. 585 - 586 (2007/10/02)
α-Selenoalkyllithiums already used for the regioselective synthesis of epoxides are found valuable building blocks for the synthesis of higher homologues namely oxetanes and tetrahydrofuranes.The general synthetic strategy used is schematized below and re
