N-((1R,2R)-2-(3-((1R,2R)-2-(Dimethylamino)cyclohexyl)thioureido)-1,2-diphenylethyl)-3,5-bis(trifluoromethyl)benzenesulfonamide functions as a chiral bifunctional organocatalyst in asymmetric synthesis.
Check Digit Verification of cas no
The CAS Registry Mumber 1020665-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,6,6 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1020665-73:
(9*1)+(8*0)+(7*2)+(6*0)+(5*6)+(4*6)+(3*5)+(2*7)+(1*3)=109
109 % 10 = 9
So 1020665-73-9 is a valid CAS Registry Number.

Chiral amine-thioureas bearing multiple hydrogen bonding donors: Highly efficient organocatalysts for asymmetric Michael addition of acetylacetone to nitroolefins
Wang, Chun-Jiang,Zhang, Zhi-Hai,Dong, Xiu-Qin,Wu, Xiao-Jun
, p. 1431 - 1433 (2008/12/21)
New bifunctional organocatalysts amine-thioureas bearing multiple hydrogen bonding donors were synthesized and applied in catalytic asymmetric Michael addition of acetylacetone to aryl and alkyl nitroolefins. Multiple hydrogen bonding donors play a signif
