Check Digit Verification of cas no

The CAS Registry Mumber 55537-61-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,3 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55537-61:
(7*5)+(6*5)+(5*5)+(4*3)+(3*7)+(2*6)+(1*1)=136
136 % 10 = 6
So 55537-61-6 is a valid CAS Registry Number.

Peptide-catalyzed regio- and enantioselective reduction of α,β,γ,δ-unsaturated aldehydes

Akagawa, Kengo,Sen, Jun,Kudo, Kazuaki

supporting information, p. 11585 - 11588 (2013/11/06)

A resin-supported peptide catalyst (see box in the scheme) was used in the title reaction. The inherent regioselectivity was overcome by the peptide catalyst to promote the 1,6-selective reaction prior to 1,4-reduction. High stereoconvergence was also achieved when using a mixture of geometric isomers of the starting aldehydes. Ach=1-amino-1-cyclohexanecarboxylic acid. Copyright
