Check Digit Verification of cas no

The CAS Registry Mumber 40576-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,7 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40576-40:
(7*4)+(6*0)+(5*5)+(4*7)+(3*6)+(2*4)+(1*0)=107
107 % 10 = 7
So 40576-40-7 is a valid CAS Registry Number.

Synthesis of (3S*,4R*,6E,10Z)-3,4,7,11-tetramethyltrideca6,10-dienal (faranal) using stereospecific 1,4-cis-hydrogenation of conjugated double bonds

Vasil'ev, Andrei A.,Engman, Lars,Serebryakov, Edward P.

, p. 2211 - 2216 (2000)

(±)-Faranal was synthesised by a convergent route involving 1,4-cis-hydrogenation of two properly substituted conjugated diene building blocks to introduce stereospecifically the 6(E) and 10(Z) double bonds of the final target molecule. meso-2,3-Dimethyls

Regio- and Stereoselective Allylic Substitutions of Chiral Secondary Alkylcopper Reagents: Total Synthesis of (+)-Lasiol, (+)-13-Norfaranal, and (+)-Faranal

Skotnitzki, Juri,Spessert, Lukas,Knochel, Paul

, p. 1509 - 1514 (2019/01/05)

Chiral secondary alkylcopper reagents were prepared from chiral secondary alkyl iodides by a retentive I/Li exchange followed by a retentive transmetalation with CuBr?P(OEt)3. Switching the solvent to THF significantly increased their configura
