1131711-66-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131711-66-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,7,1 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1131711-66:
(9*1)+(8*1)+(7*3)+(6*1)+(5*7)+(4*1)+(3*1)+(2*6)+(1*6)=104
104 % 10 = 4
So 1131711-66-4 is a valid CAS Registry Number.

Concise asymmetric synthesis of (-)-deoxoprosophylline
Liu, Ru-Cheng,Wei, Jin-Hu,Wei, Bang-Guo,Lin, Guo-Qiang
experimental part, p. 2731 - 2734 (2009/04/07)
An efficient asymmetric synthesis of the 2-hydroxymethyl 3,6-disubstituted piperidine alkaloid, (-)-deoxoprosophylline, is described. The key step of this route is the SmI2-mediated cross-coupling of chiral N-tert-butanesulfinyl imine 9 with al
