Check Digit Verification of cas no

The CAS Registry Mumber 1178541-59-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,8,5,4 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1178541-59:
(9*1)+(8*1)+(7*7)+(6*8)+(5*5)+(4*4)+(3*1)+(2*5)+(1*9)=177
177 % 10 = 7
So 1178541-59-7 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.
