Check Digit Verification of cas no

The CAS Registry Mumber 24808-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,0 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 24808-74:
(7*2)+(6*4)+(5*8)+(4*0)+(3*8)+(2*7)+(1*4)=120
120 % 10 = 0
So 24808-74-0 is a valid CAS Registry Number.

Allylic Substitution Catalyzed by a New Molybdenum Complex

Dvorakova, Hana,Dvorak, Dalimil,Srogl, Jiri,Kocovsky, Pavel

, p. 6351 - 6354 (1995)

A new molybdenum(II) complex (E), generated in situ from Mo(CO)6 by sequential treatment with PhCH2(Et)3N+Cl- and CF3SO3Ag (3 equiv.), has been found to catalyze the substitution of allylic acetates with MeOH (4 -> 5 8; 9

Nickel-Catalyzed Arylation of C(sp3)-O Bonds in Allylic Alkyl Ethers with Organoboron Compounds

Li, Xiaowei,Li, Yuxiu,Zhang, Zhong,Shi, Xiaolin,Liu, Ruihua,Wang, Zemin,Li, Xiangqian,Shi, Dayong

supporting information, p. 6612 - 6616 (2021/09/02)

A nickel-catalyzed cross-coupling of allylic alkyl ethers with organoboron compounds through the cleavage of the inert C(sp3)-O(alkyl) bonds is described. Several types of allylic alkyl ethers can be coupled with various boronic acids or their derivatives to give the corresponding products in good to excellent yields with wide functional group tolerance and excellent regioselectivity. The gram-scale reaction and late-stage modification of biologically active compounds further prove the practicality of this synthetic method.

Oxidative cleavage of allyl ethers by an oxoammonium salt

Kelly, Christopher B.,Ovian, John M.,Cywar, Robin M.,Gosselin, Taylor R.,Wiles, Rebecca J.,Leadbeater, Nicholas E.

supporting information, p. 4255 - 4259 (2015/04/14)

A method to oxidatively cleave allyl ethers to their corresponding aldehydes mediated by an oxoammonium salt is described. Using a biphasic solvent system and mild heating, cleavage proceeds readily, furnishing a variety of α,β-unsaturated aldehydes and ketones.
