1428850-52-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1428850-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,8,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1428850-52:
(9*1)+(8*4)+(7*2)+(6*8)+(5*8)+(4*5)+(3*0)+(2*5)+(1*2)=175
175 % 10 = 5
So 1428850-52-5 is a valid CAS Registry Number.

Asymmetric total synthesis of (-)-amphidinolide v through effective combinations of catalytic transformations
Volchkov, Ivan,Lee, Daesung
, p. 5324 - 5327 (2013)
An asymmetric total synthesis of (-)-amphidinolide V was accomplished. The synthesis features a base-catalyzed alkynyl silane alcoholysis/ring-closing enyne metathesis sequence for facile construction of a 1,3-diene motif. A diene RCM followed by a ring-c
