Check Digit Verification of cas no

The CAS Registry Mumber 1400791-58-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,7,9 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1400791-58:
(9*1)+(8*4)+(7*0)+(6*0)+(5*7)+(4*9)+(3*1)+(2*5)+(1*8)=133
133 % 10 = 3
So 1400791-58-3 is a valid CAS Registry Number.

Ring-closing metathesis/isomerization/pictet-spengler cascade via ruthenium/chiral phosphoric acid sequential catalysis

Cai, Quan,Liang, Xiao-Wei,Wang, Shou-Guo,Zhang, Jun-Wei,Zhang, Xiao,You, Shu-Li

, p. 5022 - 5025,4 (2012/12/12)

Chiral phosphoric acid worked together with Hoveyda-Grubbs II catalyst enabling highly efficient synthesis of enantioenriched tetrahydro-β- carbolines (up to 98% yield, 99% ee) through a ring-closing metathesis/ isomerization/Pictet-Spengler cascade reaction via sequential catalysis.
