Check Digit Verification of cas no

The CAS Registry Mumber 56752-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,7,5 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 56752-28:
(7*5)+(6*6)+(5*7)+(4*5)+(3*2)+(2*2)+(1*8)=144
144 % 10 = 4
So 56752-28-4 is a valid CAS Registry Number.

Oxidation of sulfides to sulfoxides with 3-aryl-2-tert-butyloxaziridines under high pressure

Shimizu, Masao,Shibuya, Isao,Taguchi, Yoichi,Hamakawa, Satoshi,Suzuki, Kunio,Hayakawa, Takashi

, p. 3491 - 3492 (2007/10/03)

3-Phenyl-2-tert-butyloxaziridine has been shown to behave as an oxidant under 800 MPa at 100°C to oxidize sulfides to sulfoxides, in spite of having been reported to be inactive as an oxidant and to undergo thermal rearrangement to W-tert-butyl-α-phenylnitrone at atmospheric pressure. It has been shown that under thermal and high-pressure conditions the ability of the oxaziridine to react changes dramatically. The mechanism for the high-pressure reaction is also discussed.
