1201890-27-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1201890-27-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,8,9 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1201890-27:
(9*1)+(8*2)+(7*0)+(6*1)+(5*8)+(4*9)+(3*0)+(2*2)+(1*7)=118
118 % 10 = 8
So 1201890-27-8 is a valid CAS Registry Number.

Highly efficient asymmetric epoxidation of electron-deficient α,β-enones and related applications to organic synthesis

Zheng, Changwu,Li, Yawen,Yang, Yingquan,Wang, Haifeng,Cui, Haifeng,Zhang, Junkang,Zhao, Gang

supporting information; experimental part, p. 1685 - 1691 (2011/02/25)

The asymmetric epoxidation of electrondeficient olefins has been achieved using inexpensive and readily available prolinols as catalysts with good to excellent yields and enantioselectivities. The utility of the resulting chiral epoxides was illustrated b
