Check Digit Verification of cas no

The CAS Registry Mumber 21961-03-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,6 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21961-03:
(7*2)+(6*1)+(5*9)+(4*6)+(3*1)+(2*0)+(1*3)=95
95 % 10 = 5
So 21961-03-5 is a valid CAS Registry Number.

Diaryl diselenides and related compounds as oxygen-transfer agents

Giurg, Mirosaw,Syper, Ludwik

, p. 970 - 985 (2008)

The progress in application of diaryl diselenides and related compounds as transfer agents is presented. The review is limited to the diaryl diselenides having electron-withdrawing substituents, such as nitro, trifluoromethyl, carbamoylphenyl, and polymeric diselenides PADS and PPDS. The methods of their synthesis are described. These compounds are used as effective catalyst for a simple and multi-electron hydroperoxide oxidation of different organic compounds. Transformation of functional groups, cycloalkanones ring contraction, cyclocondensation and degradation of electron-rich arenes is described. Mechanisms of the reactions involved Se(II) and Se(IV) intermediates are discussed.

Photoregulation of Gene Expression with Amantadine-Modified Caged siRNAs through Host–Guest Interactions

Zhang, Jinhao,Jing, Nannan,Fan, Xinli,Tang, Xinjing

supporting information, p. 14002 - 14010 (2020/10/02)

RNA interference is an essential and powerful tool for targeting and verifying specific gene functions. Conditional control of small interfering RNA (siRNA) activity, especially using light activation, is a potential method for regulating target gene expr

Cyclopropenone catalyzed substitution of alcohols with mesylate ion

Nacsa, Eric D.,Lambert, Tristan H.

supporting information, p. 38 - 41 (2013/03/28)

The cyclopropenone catalyzed nucleophilic substitution of alcohols by methanesulfonate ion with inversion of configuration is described. This work provides an alternative to the Mitsunobu reaction that avoids the use of azodicarboxylates and generation of hydrazine and phosphine oxide byproducts. This transformation is shown to be compatible with a range of functionality. A cyclopropenone scavenge strategy is demonstrated to aid purification.
