Check Digit Verification of cas no

The CAS Registry Mumber 1357262-40-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,2,6 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1357262-40:
(9*1)+(8*3)+(7*5)+(6*7)+(5*2)+(4*6)+(3*2)+(2*4)+(1*0)=158
158 % 10 = 8
So 1357262-40-8 is a valid CAS Registry Number.

Mukaiyama-Michael reactions with acrolein and methacrolein: A catalytic enantioselective synthesis of the C17-C28 fragment of pectenotoxins

Kemppainen, Eeva K.,Sahoo, Gokarneswar,Valkonen, Arto,Pihko, Petri M.

supporting information; experimental part, p. 1086 - 1089 (2012/03/27)

Enantioselective iminium-catalyzed reactions with acrolein and methacrolein are rare. A catalytic enantioselective Mukaiyama-Michael reaction that readily accepts acrolein or methacrolein as substrates, affording the products in good yields and 91-97% ee, is presented. As an application of the methodology, an enantioselective route to the key C17-C28 segment of the pectenotoxin using the Mukaiyama-Michael reaction as the key step is described.
