133775-92-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133775-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,7 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133775-92:
(8*1)+(7*3)+(6*3)+(5*7)+(4*7)+(3*5)+(2*9)+(1*2)=145
145 % 10 = 5
So 133775-92-5 is a valid CAS Registry Number.

Diastereoselectivity in Nucleophilic Addition Reactions to (α,β-Dialkoxyacyl)silanes: An Operationally Useful Route to Optically Active 1,2,3-syn-Triols
Cirillo, Pier F.,Panek, James S.
, p. 6071 - 6073 (2007/10/02)
silanes 3 undergo chelation-controlled nucleophilic addition reactions to produce Cram-type addition products (1,2,3-syn-triol derivatives) 4 with useful levels of diastereoselectivity.
