Check Digit Verification of cas no

The CAS Registry Mumber 312313-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,3,1 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 312313-49:
(8*3)+(7*1)+(6*2)+(5*3)+(4*1)+(3*3)+(2*4)+(1*9)=88
88 % 10 = 8
So 312313-49-8 is a valid CAS Registry Number.

Photochemical reactions of N-acylbenzoxazole-2-thiones

Nishio, Takchiko,Iida, Ikuo,Sugiyama, Kunjo

, p. 3039 - 3046 (2007/10/03)

The photochemical reactions of N-acylbenzoxazole-Z-thiones 1 are examined. Irradiation of N-acylbenzoxazole-2-thiones 1 in the presence of a variety of alkenes 2 yields 2-substituted benzoxazoles 3-20 and/or the unexpected products, iminothietanes 21-29 by intramolecular trapping of the acyl group by thiolate anion of the zwitterionic intermediate I and by the phenolate anion of the zwitterionic intermediate II, respectively, derived from the spirocyclic aminothietanes AT which are formed by regioselective [2+2] cycloaddition of the carbon-sulfur double bond of 1 to the alkene double bond.
