130984-56-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130984-56-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,8 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130984-56:
(8*1)+(7*3)+(6*0)+(5*9)+(4*8)+(3*4)+(2*5)+(1*6)=134
134 % 10 = 4
So 130984-56-4 is a valid CAS Registry Number.

Addition reactions of chloro- Or iodomethyllithium to imines. Synthesis of enantiopure aziridines and β-chloroamines

Concellon, Jose M.,Rodriguez-Solla, Humberto,Bernad, Pablo L.,Simal, Carmen

experimental part, p. 2452 - 2459 (2009/07/18)

We report a novel, simple, and efficient synthesis of aziridines and l-chloroalkan-2-amines by the reaction of imines derived from various aldehydes and p-toluenesulfonamide or benzenesulfonamide with iodoor chloromethyllithium, respectively. Both halogenated anions were generated in situ by treatment of diiodo- or chloroiodomethane with methyllithium at -78 or 0 °C. The reaction of in situ generated iodoor chloromethyllithium could also be performed from chiral 2-aminoaldimines to yield enantiopure aziridines or (2S,3S)-2,3-diamino- l-chloroalkanes with high stereoselectivity.
