Check Digit Verification of cas no
The CAS Registry Mumber 203-85-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 203-85:
(5*2)+(4*0)+(3*3)+(2*8)+(1*5)=40
40 % 10 = 0
So 203-85-0 is a valid CAS Registry Number.

A facile, high-yielding method for the conversion of halides to mercaptans
Bieniarz,Cornwell
, p. 939 - 942 (2007/10/02)
An efficient, high-yield, one-pot preparation of alkyl and activated aryl mercaptans is presented. The method relies on sodium thiophosphate displacement of the halide, followed by mild hydrolysis of the intermediate phosphorothioate.
Ramberg-Baecklund Reaction of 1,3-Dibromo-1H,3H-naphthothiopyran 2,2-Dioxide. Formation of Acenaphthyne Intermediate
Nakayama, Juzo,Ohshima, Etsuo,Ishii, Akihiko,Hoshino, Masamatsu
, p. 60 - 65 (2007/10/02)
Radical bromination of 1H,3H-naphthothiopyran 2,2-dioxide (15) gave the corresponding monobromo sulfone 16 (48percent), dibromo sulfone 12 (43percent; cis/trans = 64/36), and tribromo sulfone 17 (5percent).Ramberg-Baecklund reaction of 12 was investigated under a variety of coditions with expectation of the formation of thiirene dioxide 11 from which generation of acenaphthyne (5) would be expected both thermally and photochemically.Observed characteristic features of the reaction are as follows: (i) the use of triethylamine as base yielded 1-bromo-acenaphthylene (20; 39percent) and debrominated products 15 (5percent) and 16 (9percent); (ii) the use of sodium methoxide as base afforded decacyclene (3) surprisingly, though in a trace amount, in addition to 20 (75percent) and acenaphthylene (18; 9percent); (iii) the use of potassium tert-butoxide as base gave an improved yield of 3 (5percent) along with 20 (36percent) and 18 (27percent).The formation of 3 may best be rationalized by assuming the generation of acenaphthyne intermediate 5 from 11 by loss of sulfur dioxide.
