844645-03-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 844645-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,4,6,4 and 5 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 844645-03:
(8*8)+(7*4)+(6*4)+(5*6)+(4*4)+(3*5)+(2*0)+(1*3)=180
180 % 10 = 0
So 844645-03-0 is a valid CAS Registry Number.

Asymmetric palladium-catalyzed hydrosilylation of styrenes using efficient chiral spiro phosphoramidite ligands

Guo, Xun-Xiang,Xie, Jian-Hua,Hou, Guo-Hua,Shi, Wen-Jian,Wang, Li-Xin,Zhou, Qi-Lin

, p. 2231 - 2234 (2007/10/03)

Asymmetric hydrosilylation of styrene derivatives with trichlorosilane in the presence of palladium complexes of chiral spiro phosphoramidites provided 1-aryl-1-silylalkanes as single regioisomers in high yields, which have been oxidized with hydrogen peroxide to give the corresponding chiral alcohols in up to 99.1% ee.
