Check Digit Verification of cas no

The CAS Registry Mumber 803706-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,3,7,0 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 803706-21:
(8*8)+(7*0)+(6*3)+(5*7)+(4*0)+(3*6)+(2*2)+(1*1)=140
140 % 10 = 0
So 803706-21-0 is a valid CAS Registry Number.

Synthesis and evaluation of guanidinyl pyrrolidines as bifunctional catalysts for enantioselective conjugate additions to cyclic enones

Pansare, Sunil V.,Lingampally, Rajinikanth

, p. 319 - 324 (2009)

Guanidinyl pyrrolidines derived from 'S'-proline are effective catalysts for the enantioselective conjugate addition of malonate, nitroalkane and other carbon and heteroatom nucleophiles to cyclohexenone and cyclopentenone in the absence of basic additive

Optimization of the catalytic asymmetric addition of nitroalkanes to cyclic enones with trans-4,5-methano-L-proline

Hanessian, Stephen,Shao, Zhihui,Warrier, Jayakumar S.

(Chemical Equation Presented) The conjugate addition of symmetrical 2-nitroalkanes to 2-cycloalkenones catalyzed by trans-4,5-methano-L-proline proceeds with >99% ee and excellent chemical yields. 1-Nitroalkanes afford diastereomeric syn/anti products tha

4-trans-Amino-proline based di- and tetrapeptides as organic catalysts for asymmetric C-C bond formation reactions

Tsogoeva, Svetlana B.,Jagtap, Sunil B.,Ardemasova, Zoya A.

, p. 989 - 992 (2007/10/03)

4-trans-Amino-proline based di- and tetrapeptides have been successfully applied as chiral organocatalysts in the enantioselective conjugate addition of nitroalkanes to cyclic enones and the direct aldol reaction. Two 4-trans-amino-proline residues were s

Trends in asymmetric Michael reactions catalysed by tripeptides in combination with an achiral additive in different solvents

Tsogoeva, Svetlana B.,Jagtap, Sunil B.,Ardemasova, Zoya A.,Kalikhevich, Victor N.
