501084-20-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 501084-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,0,8 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 501084-20:
(8*5)+(7*0)+(6*1)+(5*0)+(4*8)+(3*4)+(2*2)+(1*0)=94
94 % 10 = 4
So 501084-20-4 is a valid CAS Registry Number.

Synthesis and conformational analysis of meso-ter(1,3-dioxan-4-yls)
Hoffmann, Reinhard W.,Mas, Gemma,Brandl, Trixi
, p. 3455 - 3464 (2007/10/03)
A convergent synthesis of the meso-ter(1,3-dioxanyls) 8-11 has been achieved, starting from two enantiomeric building blocks in each case. The stereogenic centres in the central linkage region were set up by stereocontrolled aldol additions. Structure ass
