75445-61-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75445-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,4,4 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75445-61:
(7*7)+(6*5)+(5*4)+(4*4)+(3*5)+(2*6)+(1*1)=143
143 % 10 = 3
So 75445-61-3 is a valid CAS Registry Number.

Enantioselective Total Synthesis of (?)-Spiroxins A, C, and D

Chen, Chong-Chong,Hu, Xiangdong,Shu, Xin,Yang, Jiayi,Yu, Tao

supporting information, p. 18514 - 18518 (2021/07/20)

Spiroxins A, C, and D are metabolites that have been identified in the marine fungal strain LL-37H248. Their unique polycyclic structures and intriguing biological activities make them attractive targets for the synthetic community. Based on a scalable en

Enzymatic desymmetrization/resolution of epoxydiols derived from 1,4-naphthoquinone, 5-hydroxy-1,4-naphthoquinone and 5,8-dihydroxy-1,4- naphthoquinone

Betts, Russell L.,Murphy, Sean T.,Johnson, Carl R.

, p. 2853 - 2860 (2007/10/03)

The enzymatic desymmetrization/resolution of epoxydiols generated from the basic epoxidation and reduction of 1,4-naphthoquoinone, 5-hydroxy-1,4- naphthoquinone and 5,8-dihydroxy-1,4-naphthoquinone is described. 2,3-Epoxy-1α,2α,3α,4 α-tetrahydronaphthalene-1,4-diol and 5,8-diallyloxy-2,3-epoxy- 1α,2α,3α,4 α-tetrahydronaphthalene-1,4-diol were desymmetrized in the presence of isopropenyl acetate using Burholderia cepacia lipase and Candida antartica lipase B, respectively. An enzymatic resolution of 8-benzyloxy-2,3-epoxy-1α,2α,3 α,4α-tetrahydronaphthalene-1,4-diol using B. cepacia lipase in isopropenyl acetate is also described.
