Check Digit Verification of cas no

The CAS Registry Mumber 52049-50-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,4 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52049-50:
(7*5)+(6*2)+(5*0)+(4*4)+(3*9)+(2*5)+(1*0)=100
100 % 10 = 0
So 52049-50-0 is a valid CAS Registry Number.

, p. 305 - 310 (2005)

The diastereoselective synthesis of (1R*,1′S*,2S*, 2′R*,5S*,5′R*,8R*,8′S*)-bis-1, 4-{1-aza-5-methyl-8-(4-nitrophenyl)-3,7-dioxabicyclo[3.3.0]octane-2-yl}benzene is described as the first example of a long distance stereocontrolled synthesis of this type of structure. The thermodynamic control of the reaction together with complete NMR evidence to support the stereochemistry of this compound are discussed.
