925670-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 925670-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,5,6,7 and 0 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 925670-73:
(8*9)+(7*2)+(6*5)+(5*6)+(4*7)+(3*0)+(2*7)+(1*3)=191
191 % 10 = 1
So 925670-73-1 is a valid CAS Registry Number.

Stereoselective Synthesis of Alkylidene Phthalides
Dragan, Andrei,Jones, D. Heulyn,Kennedy, Alan R.,Tomkinson, Nicholas C. O.
, p. 3086 - 3089 (2016/07/13)
The N,O-diacylhydroxylamine derivative 4 has been prepared and its reactivity with nucleophiles investigated. On reaction with lithium enolates of cyclic or acyclic ketones, 4 is converted stereoselectively to the corresponding alkylidene phthalide. The s
