Check Digit Verification of cas no

The CAS Registry Mumber 227286-92-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,2,8 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 227286-92:
(8*2)+(7*2)+(6*7)+(5*2)+(4*8)+(3*6)+(2*9)+(1*2)=152
152 % 10 = 2
So 227286-92-2 is a valid CAS Registry Number.

Enantiospecific synthesis of (+)-ribasine

Ollero, Lourdes,Castedo, Luis,Dominguez, Domingo

, p. 4445 - 4456 (2007/10/03)

The alkaloid (+)-ribasine was synthesized by stereocontrolled addition of substituted α-lithium-o-toluate 6d to enantiomerically pure (R)-N-(9- phenylfluoren-9-yl)-2-amino-5,6-(methylenedioxy)indan-1-one [(+)-5]. Aminoindanone (+)-5 was prepared from amino acid (-)-15 obtained by diastereoselective alkylation of a chiral glyeme enolate synthon.
