Check Digit Verification of cas no

The CAS Registry Mumber 1036637-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,6,6,3 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1036637-32:
(9*1)+(8*0)+(7*3)+(6*6)+(5*6)+(4*3)+(3*7)+(2*3)+(1*2)=137
137 % 10 = 7
So 1036637-32-7 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of nitrocyclopropane carboxylates

Moreau, Benoit,Alberico, Dino,Lindsay, Vincent N.G.,Charette, Andre B.

experimental part, p. 3487 - 3496 (2012/06/04)

A Cu(I)-catalyzed asymmetric cyclopropanation of alkenes with an iodonium ylide has been developed. The copper source, hypervalent iodine source, solvent, and additives all have a significant effect on the yields and enantioselectivities. High enantioselectivity (up to 99:1 er) and diastereoselectivity (95:5 dr trans/cis) were achieved for a wide range of alkenes. Conditions were developed to convert the trans products to the cis isomers. In addition, 1-nitrocyclopropyl carboxylates were transformed into the corresponding substituted cyclopropane amino acids and aminocyclopropanes. Moreover, a comparative study between Zn- and In-mediated reduction reactions of the nitro group in these compounds with regards to the er erosion in the process is also documented.
