1372400-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1372400-45-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,4,0 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1372400-45:
(9*1)+(8*3)+(7*7)+(6*2)+(5*4)+(4*0)+(3*0)+(2*4)+(1*5)=127
127 % 10 = 7
So 1372400-45-7 is a valid CAS Registry Number.

Rhodium-catalysed enantioselective synthesis of 4-arylchroman-2-ones
Allen, Joseph C.,Kociok-Koehn, Gabriele,Frost, Christopher G.
, p. 32 - 35 (2012/01/06)
The rhodium-catalysed enantioselective 1,4-addition of organoboron reagents to arylidene Meldrum's acids as acceptors, allows convenient access to 4-arylchroman-2-ones with good to excellent levels of enantioselectivity. The use of silyl-protected dioxabo
