Check Digit Verification of cas no

The CAS Registry Mumber 1005470-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,4,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1005470-57:
(9*1)+(8*0)+(7*0)+(6*5)+(5*4)+(4*7)+(3*0)+(2*5)+(1*7)=104
104 % 10 = 4
So 1005470-57-4 is a valid CAS Registry Number.

Organocatalytic enantioselective cascade michael-aldol condensation reactions: Efficient assembly of densely functionalized chiral cyclopentenes

Wang, Jian,Li, Hao,Xie, Hexin,Zu, Liansuo,Shen, Xu,Wang, Wei

, p. 9050 - 9053 (2008/09/19)

(Chemical Equation Presented) A cascade of possibility: A novel and highly enantioselective cascade Michael-aldol condensation reaction of α,β-unsaturated aldehydes with dimethyl malonate aldehyde has been developed. The process, efficiently catalyzed by a simple chiral diphenylprolinol TES ether, serves as a powerful approach to the preparation of highly functionalized chiral cyclopentenes with the formation of two new C-C bonds. TES = triethylsilyl.
