Check Digit Verification of cas no

The CAS Registry Mumber 940003-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,0,0 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 940003-64:
(8*9)+(7*4)+(6*0)+(5*0)+(4*0)+(3*3)+(2*6)+(1*4)=125
125 % 10 = 5
So 940003-64-5 is a valid CAS Registry Number.

Asymmetric synthesis of long chain α-methyl-β-thiotrifluoromethyl ketones employing the SAMP-/RAMP-hydrazone alkylation methodology

Munoz, Lourdes,Bosch, Ma Pilar,Guerrero, Angel

, p. 651 - 658 (2007/10/03)

The enantioselective synthesis of both enantiomers of (Z)-1,1,1-trifluoro-3-methyl-4-thia-13-octadecen-2-one and (Z)-1,1,1-trifluoro-3-methyl-4-thia-13-hexadecen-2-one (ee ≥90%), potential inhibitors of the pheromone action of two major maize pests Sesamia nonagrioides and Ostrinia nubilalis, is described. The key step is based upon a stereoselective alkylation with methyl iodide using the SAMP-/RAMP-chiral auxiliary methodology, followed by deprotection under non-racemization conditions.
