Check Digit Verification of cas no

The CAS Registry Mumber 1392836-25-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,8,3 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1392836-25:
(9*1)+(8*3)+(7*9)+(6*2)+(5*8)+(4*3)+(3*6)+(2*2)+(1*5)=187
187 % 10 = 7
So 1392836-25-7 is a valid CAS Registry Number.

An asymmetric organocatalytic povarov reaction with 2-hydroxystyrenes

experimental part, p. 6970 - 6979 (2012/10/18)

An organocatalytic asymmetric three-component Povarov reaction involving 2-hydroxystyrenes has been established to provide an efficient method to access structurally diverse cis-disubstituted tetrahydroquinolines in high stereoselectivities of up to >99:1 dr and 97% ee. This protocol also provides an easy access to tetrahydroquinolines with chiral quaternary stereocenters upon using α-alkyl 2-hydroxystyrenes as substrates. The theoretical studies revealed that the Povarov reaction proceeded through a sequential vinylogous Mannich reaction and an intramolecular Friedel-Crafts reaction, wherein the phosphoric acid acted as bifunctional catalyst to activate 2-hydroxystyrene and aldimine simultaneously.
