769923-44-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 769923-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,9,9,2 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 769923-44:
(8*7)+(7*6)+(6*9)+(5*9)+(4*2)+(3*3)+(2*4)+(1*4)=226
226 % 10 = 6
So 769923-44-6 is a valid CAS Registry Number.

, p. 1695 - 1698 (2004)
A novel procedure for the synthesis of cis-bicyclic spirocyclopropanelactones from cyclopropylidenyl aldehydes via the molybdenum-mediated cyclocarbonylation is described. The use of (C 7H8)Mo(CO)3 with DMSO to promote the
