22156-44-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22156-44-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22156-44:
(7*2)+(6*2)+(5*1)+(4*5)+(3*6)+(2*4)+(1*4)=81
81 % 10 = 1
So 22156-44-1 is a valid CAS Registry Number.

Low-Valent Titanium-Mediated Radical Conjugate Addition Using Benzyl Alcohols as Benzyl Radical Sources

Suga, Takuya,Shimazu, Shoma,Ukaji, Yutaka

supporting information, p. 5389 - 5392 (2018/09/12)

A concise method to directly generate benzyl radicals from benzyl alcohol derivatives has been developed. The simple and inexpensive combination of TiCl4(collidine) (collidine = 2,4,6-collidine) and manganese powder afforded a low-valent titanium reagent, which facilitated homolytic cleavage of benzylic C-OH bonds. The application to radical conjugate addition reactions demonstrated the broad scope of this method. The reaction of various benzyl alcohol derivatives with electron-deficient alkenes furnished the corresponding radical adducts.

4,5-DIHYDRONAPHTHO [1,2-b] THIOPHENE DERIVATIVE

-

Page/Page column 10-11, (2010/11/08)

A 4,5-dihydronaphtho[1,2-b]thiophene derivative expressed by the formula: (wherein R1 is a C1 to C10 1-hydroxyalkyl group or a C1 to C10 acyl group, and R2 and R3 separately substitute in the 6-, 7-, 8-, or 9-positions, and are each independently a hydrogen atom, a halogen atom, a C1 to C10 alkyl group, a hydroxy group, a C1 to C10 alkoxy group, a C1 to C5 alkenyloxy group, a C1 to C5 alkynyloxy group, a benzyloxy group, or the like, provided that when R1 is an acyl group and R2 is a hydrogen atom, then R3 is neither a hydrogen atom nor an acetyl group), or a pharmaceutically acceptable salt thereof. This is a novel compound that is effective in reducing triglyceride levels in the liver and reducing blood glucose levels.
