161754-49-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161754-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,5 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161754-49:
(8*1)+(7*6)+(6*1)+(5*7)+(4*5)+(3*4)+(2*4)+(1*9)=140
140 % 10 = 0
So 161754-49-0 is a valid CAS Registry Number.

Asymmetric synthesis using reactions with modest group selectivity
Ward, Dale E.,Liu, YaDong,Rhee, Chung K.
, p. 1429 - 1446 (2007/10/02)
The isomeric purity of products from certain group-selective reactions can be significantly amplified when reactions can occur sequentially.The theoretical basis for a strategy that exploits reactions with modest enantiotopic group selectivity for asymmet
