Check Digit Verification of cas no

The CAS Registry Mumber 1133717-75-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,7,1 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1133717-75:
(9*1)+(8*1)+(7*3)+(6*3)+(5*7)+(4*1)+(3*7)+(2*7)+(1*5)=135
135 % 10 = 5
So 1133717-75-5 is a valid CAS Registry Number.

Rationally designed 4-phenoxy substituted prolinamide phenols organocatalyst for the direct aldol reaction in water

Zhang, Shu-peng,Fu, Xiang-kai,Fu, Shao-dong

supporting information; experimental part, p. 1173 - 1176 (2009/06/28)

A rationally designed 4-phenoxy substituted prolinamide phenols as an efficient hydrophobic organocatalyst for direct asymmetric aldol reaction in water has been developed. High yield (up to 99%), diastereoselectivity (up to 99:1), and enantioselectivity (up to 97%) were obtained under optimal condition. The influence of substituent groups on the reactivity of catalysts was studied in detail. Crown Copyright
