143585-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143585-44-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 143585-44:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*5)+(2*4)+(1*4)=138
138 % 10 = 8
So 143585-44-8 is a valid CAS Registry Number.

MgBr2-promoted enantioselectIVe aryl addition of ArTi(OiPr)3 to ketones catalyzed by a titanium(IV) catalyst of N,N′-sulfonylated (1R,2R)-cyclohexane-1,2-diamine

Shu, Chao-Chi,Zhou, Shuangliu,Gau, Han-Mou

, p. 98391 - 98398 (2015/12/04)

MgBr2-promoted asymmetric addition of ArTi(OiPr)3 to ketones catalyzed by a titanium catalyst of N,N′-sulfonylated (1R,2R)-cyclohexane-1,2-diamines is reported, and results showed that the chiral N,N′-sulfonylated cyclohex

Catalytic enantioselective cyclopropanation with bis(halomethyl) zinc reagents. II. The effect of promoter structure on selectivity

Denmark, Scott E.,Christenson, Beritte L.,O'Connor, Stephen P.

, p. 2219 - 2222 (2007/10/02)

The catalytic, enantioselective cyclopropanation of cinnamyl alcohol has been accomplished with bis (iodomethyl)zinc in the presence of chiral bis(sulfonamides) derived from cyclohexanediamine. An extensive survey of diamine and sulfonamide structure has revealed a marked sensitivity to the spatial relationship of the amine groups, but only a modest dependence on the sulfonamide residue.
