Check Digit Verification of cas no

The CAS Registry Mumber 1073258-25-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,3,2,5 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1073258-25:
(9*1)+(8*0)+(7*7)+(6*3)+(5*2)+(4*5)+(3*8)+(2*2)+(1*5)=139
139 % 10 = 9
So 1073258-25-9 is a valid CAS Registry Number.

Pd-catalyzed asymmetric hydrogenation of C=C bond of α,β- unsaturated ketones

Wang, Duo-Sheng,Wang, Da-Wei,Zhou, Yong-Gui

, p. 947 - 950 (2011/06/17)

Homogenous palladium-catalyzed asymmetric hydrogenation of C=C double bond of ,-unsaturated ketones has been -developed by using palladium(II) trifluoroacetate/(S)-7,7-bis-[di(4-methoxyphenyl]phosphino)-1,1-spirobiindane complex [Pd(OCOCF3)2-(S)-An-SDP] as the catalyst under ambient hydrogen pressure and room temperature with up to 89% ee.
