75250-34-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75250-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75250-34:
(7*7)+(6*5)+(5*2)+(4*5)+(3*0)+(2*3)+(1*4)=119
119 % 10 = 9
So 75250-34-9 is a valid CAS Registry Number.

Organic Tellurium and Selenium Chemistry. Reduction of Tellurides, Selenides, and Selenoacetals with Triphenyltin Hydride

, p. 4438 - 4447 (2007/10/02)

Preparative and mechanistic details are described for the conversion of selenides into hydrocarbons RH> by heating with triphenyltin hydride at about 120 deg C.The process has been extended to selenoacetals in a form that constitutes a reduction methods for carbonyl compounds RR'C(SePh)2 -> RR'CH2>.Selective reduction of selenoacetals in the presence of thioacetals is possible.Cold-labeled species can be prepared by using triphenyltin deuteride.Tellurides are available easily without problems arising from exposure to air provided that the work is done in a photographic darkroom equipped with a red safety light.These tellurides, as well as the corresponding dichlorides , are reduced under very mild conditions (25-80 deg C) by triphenyltin hydride.The selenium- and tellurium-based chemistry has been used for the unusual process of reducing an epoxide in the presence of a ketone carbonyl.
