Check Digit Verification of cas no

The CAS Registry Mumber 205063-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,0,6 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 205063-90:
(8*2)+(7*0)+(6*5)+(5*0)+(4*6)+(3*3)+(2*9)+(1*0)=97
97 % 10 = 7
So 205063-90-7 is a valid CAS Registry Number.

Synthesis of optically active arylene bis-alanine derivatives carrying orthogonal protecting groups

Ritzen, Andreas,Basu, Basudeb,Chattopadhyay, Shital K.,Dossa, Fahreen,Frejd, Torbjoern

, p. 503 - 512 (2007/10/03)

Derivatives of para- and meta-phenylene bis-alanine and related biphenyl systems, carrying four orthogonal protecting groups, were synthesised via combinations of Heck couplings and asymmetric hydrogenations. The intermediate unsaturated arylalanine derivatives were hydrogenated using [Rh(COD)((R,R)-DIPAMP)]+BF4- or [Rh(COD)(Me-DuPHOS)]+X- as catalysts to produce the optically active, protected amino acid derivatives in ≤98% e.e. as analysed by chiral phase HPLC.
