Check Digit Verification of cas no
The CAS Registry Mumber 861337-57-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,3,3 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 861337-57:
(8*8)+(7*6)+(6*1)+(5*3)+(4*3)+(3*7)+(2*5)+(1*7)=177
177 % 10 = 7
So 861337-57-7 is a valid CAS Registry Number.

Halogenation Reaction of S-Aryl-Ssulfoximide
Yoshida, Toyokichi,Naruto, Shunsuke,Uno, Hitoshi,Nishimura, Haruki
, p. 1175 - 1182 (2007/10/02)
The reactions of the title free sulfoximide with N-bromosuccinimide (NBS) and N-chlorosuccinimide (NCS) afforded the corresponding α-halogenated "free" sulfoximides in good yields.The α-bromination proceeded via a facile N-bromination followed by a bromine transfer reaction of the resulting N-bromosulfoximide.The NCS chlorination, in contrast, proceeded via direct α-chlorination, not via N-chlorination.However, in the presence of potassium carbonate or silica gel N-chlorination occured predominantly in the NCS chlorination.Keywords---1,2-benzisoxazole; halogenation; N-halosulfoximide; α-halo sulfoximide; rearrangement; induction period
