Check Digit Verification of cas no

The CAS Registry Mumber 1403266-85-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,2,6 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1403266-85:
(9*1)+(8*4)+(7*0)+(6*3)+(5*2)+(4*6)+(3*6)+(2*8)+(1*5)=132
132 % 10 = 2
So 1403266-85-2 is a valid CAS Registry Number.

Cu-Catalyzed Hydroxymethylation of Unactivated Alkyl Iodides with CO To Provide One-Carbon-Extended Alcohols

Zhao, Siling,Mankad, Neal P.

, p. 5867 - 5870 (2018)

We have developed a reductive carbonylation method by which unactivated alkyl iodides can be hydroxymethylated to provide one-carbon-extended alcohol products under Cu-catalyzed conditions. The method is tolerant of alkyl β-hydrogen atoms, is robust towards a wide variety of functional groups, and was applied to primary, secondary, and tertiary alkyl iodide substrates. Mechanistic experiments indicate that the transformation proceeds by atom-transfer carbonylation (ATC) of the alkyl iodide followed in tandem by two CuH-mediated reductions in rapid succession. This radical mechanism renders the Cu-catalyzed system complementary to precious-metal-catalyzed reductive carbonylation reactions.

Copper-catalyzed reduction of alkyl triflates and iodides: An efficient method for the deoxygenation of primary and secondary alcohols

Dang, Hester,Cox, Nick,Lalic, Gojko

supporting information, p. 752 - 756 (2014/01/23)

We describe an effective method for catalytic reduction of 1°alkyl sulfonates, and 1°and 2°iodides in the presence of a wide range of functional groups. This Cu-catalyzed reaction provides a means for the effective deoxygenation of alcohols, as demonstrated by the highly selective reduction of 1°alcohols using a triflation/reduction sequence. A preliminary study of the reaction mechanism suggests that the reduction does not involve free-radical intermediates.
