Check Digit Verification of cas no

The CAS Registry Mumber 14771-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,7 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14771-22:
(7*1)+(6*4)+(5*7)+(4*7)+(3*1)+(2*2)+(1*2)=103
103 % 10 = 3
So 14771-22-3 is a valid CAS Registry Number.

Direct Access to N -Alkylsulfoximines from Sulfides by a Sequential Imidation/Oxidation Procedure

Dannenberg, Carl Albrecht,Bizet, Vincent,Bolm, Carsten

, p. 1951 - 1959 (2015/06/30)

Synthetically relevant N-alkyl-substituted sulfoximines are directly prepared from sulfides by an unprecedented one-pot imidation/oxidation sequence. In situ generated N-bromoalkylamines serve as readily accessible imidating agents leading to N-alkylsulfiliminium bromides that are subsequently oxidized providing the corresponding N-alkylsulfoximines. In this manner, gram quantities of the products can be obtained in a short period of time avoiding the use of toxic and cumbersome to handle alkylating reagents.
