274682-96-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 274682-96-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,4,6,8 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 274682-96:
(8*2)+(7*7)+(6*4)+(5*6)+(4*8)+(3*2)+(2*9)+(1*6)=181
181 % 10 = 1
So 274682-96-1 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.
