Check Digit Verification of cas no

The CAS Registry Mumber 1376253-63-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,6,2,5 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1376253-63:
(9*1)+(8*3)+(7*7)+(6*6)+(5*2)+(4*5)+(3*3)+(2*6)+(1*3)=172
172 % 10 = 2
So 1376253-63-2 is a valid CAS Registry Number.

Hydrosilylation of Carbonyls Catalyzed by Hydridoborenium Borate Salts: Lewis Acid Activation and Anion Mediated Pathways

Rawat, Sandeep,Bhandari, Mamta,Porwal, Vishal Kumar,Singh, Sanjay

supporting information, p. 7195 - 7203 (2020/05/18)

The electronically unsaturated three-coordinated hydridoborenium cations [LBH]+[HB(C6F5)3]-(1) and [LBH]+[B(C6F5)4]-(2), supported by a bis(phosphinimino)amide ligand, were found to be excellent catalysts for hydrosilylation of a range of aliphatic and ar

Catalytic hydrosilylation of carbonyls via Re(CO)5Cl photolysis

Toh, Chun Keong,Sum, Yin Ngai,Fong, Wai Kit,Ang, Siau Gek,Fan, Wai Yip

experimental part, p. 3880 - 3887 (2012/07/02)

The hydrosilylation reaction between silanes and various carbonyl substrates such as aldehyde, ketone, ester, and carbonate has been catalyzed by Re(CO)5Cl UV photolysis. Kinetic studies have shown that the reaction is favored for the least sterically hindered silanes with aldehydes followed by aliphatic ketones. The IR spectrum of the rhenium carbonyl dimer HRe 2(CO)9(SiR3) has been recorded in the reaction mixture. This complex is believed to be the resting state of the active catalyst Re(CO)4SiR3, which could be released upon photactivation. A catalytic mechanism involving this species has been proposed and shown to be thermodynamically feasible using computational studies. In addition, the relative hydrosilylation rates among the various carbonyl substrates can be explained using the same mechanism.
