1241048-42-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1241048-42-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,0,4 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1241048-42:
(9*1)+(8*2)+(7*4)+(6*1)+(5*0)+(4*4)+(3*8)+(2*4)+(1*2)=109
109 % 10 = 9
So 1241048-42-9 is a valid CAS Registry Number.

Bray, Christopher D.,Minicone, Fabrizio
supporting information; experimental part, p. 5867 - 5869 (2010/10/21)
Treatment of a variety of enantiopure terminal epoxides with the anion of a range of 2-substituted triethylphosphonoacetates leads to an array of quaternary cyclopropyl esters with high yield and diastereocontrol.
