357407-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 357407-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,4,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 357407-83:
(8*3)+(7*5)+(6*7)+(5*4)+(4*0)+(3*7)+(2*8)+(1*3)=161
161 % 10 = 1
So 357407-83-1 is a valid CAS Registry Number.

Toward the creation of NMR databases in chiral solvents for assignments of relative and absolute stereochemistry: proof of concept.

Kobayashi,Hayashi,Tan,Kishi

, p. 2245 - 2248 (2007/10/03)

[structure: see text] An NMR database approach in a chiral solvent allows us to predict both relative and absolute stereochemistry of an unknown compound without degradation and/or derivatization. N,alpha-Dimethylbenzylamine (DMBA) is a suitable solvent for this purpose. Using the C.5-C.10 portion of oasomycin A, the feasibility and reliability of this approach is demonstrated.
