Check Digit Verification of cas no

The CAS Registry Mumber 186192-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,1,9 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 186192-49:
(8*1)+(7*8)+(6*6)+(5*1)+(4*9)+(3*2)+(2*4)+(1*9)=164
164 % 10 = 4
So 186192-49-4 is a valid CAS Registry Number.

Reaction of electronically stabilized thiones with benzyne. The isolation of thiobenzophenone-benzyne and thiopivalophenone-benzyne adducts

Okuma, Kentaro,Shiki, Kyoko,Sonoda, Shinya,Koga, Yuji,Shioji, Kosei,Kitamura, Tsugio,Fujiwara, Yuzo,Yokomori, Yoshinobu

, p. 155 - 161 (2000)

The reaction of thiobenzophenones (1) with phenyl[2- (trimethylsilyl)phenyl]iodonium trifluoromethanesulfonate (4) in the presence of tetrabutylammonium fluoride afforded the corresponding [4+2] cycloadducts, which are the first examples of thiobenzophenone-benzyne adducts. The reaction of thiopivalophenone (6) with benzyne prepared from 4 and tetrabutylammonium fluoride at room temperature gave [2+2] cycloadducts (7). When the reaction was carried out in refluxing dichloromethane, a mixture of 7 and [4+2] cycloadducts (13) was obtained.
