Check Digit Verification of cas no

The CAS Registry Mumber 504404-77-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,4,4,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 504404-77:
(8*5)+(7*0)+(6*4)+(5*4)+(4*0)+(3*4)+(2*7)+(1*7)=117
117 % 10 = 7
So 504404-77-7 is a valid CAS Registry Number.

Tandem olefin migration-aldol condensation in water with an amphiphilic resin-supported ruthenium complex

Oe, Yohei,Uozumi, Yasuhiro

, p. 787 - 790 (2011)

A catalytic tandem olefin migration-aldol condensation process with allylic carbinols and aryl aldehydes was performed with 0.5 mol% of an amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin supported phosphine-ruthenium complex in water as a single reaction medium under heterogeneous conditions to give the corresponding aldols with syn selectivity. Inverse stereoselectivity (anti selectivity) was observed when the reaction was carried out in the presence of KO Georg Thieme Verlag Stuttgart.

Aldol- and Mannich-type reactions via in situ olefin migration in ionic liquid.

Yang, Xiao-Fan,Wang, Mingwen,Varma, Rajender S,Li, Chao-Jun

, p. 657 - 660 (2007/10/03)

An aldol-type and a Mannich-type reaction via the cross-coupling of aldehydes and imines with allylic alcohols catalyzed by RuCl(2)(PPh(3))(3) was developed with ionic liquid as the solvent. The solvent/catalyst system could be reused for at least five times with no loss of reactivity.
