167965-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 167965-59-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,9,6 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167965-59:
(8*1)+(7*6)+(6*7)+(5*9)+(4*6)+(3*5)+(2*5)+(1*9)=195
195 % 10 = 5
So 167965-59-5 is a valid CAS Registry Number.

Photoreactions of 1,3-Dihydroisobenzofuran-1-thiones and 1,3-Dihydro-2-benzothiophene-1-thiones with Alkenes
Nishio, Takehiko
, p. 561 - 568 (2007/10/02)
The photoreactions of isobenzofuran-1-thiones 7 and 2-benzothiophene-1-thiones 11 in the presence of alkenes have been examined.Irradiation of thiones 7 and 11 in the presence of alkenes gave spiro-thietanes 15 and 21, which are formed by cycloadd
