Check Digit Verification of cas no
The CAS Registry Mumber 117609-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,0 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117609-34:
(8*1)+(7*1)+(6*7)+(5*6)+(4*0)+(3*9)+(2*3)+(1*4)=124
124 % 10 = 4
So 117609-34-4 is a valid CAS Registry Number.

2-ARYL-1,2-DIAZETIDIN-3-ONES (AZA-β-LACTAMS) VIA GRIGNARD-INDUCED CYCLIZATION OF α-(2-ARYLHYDRAZINO)-ESTERS
Schantl, Joachim G.,Decristoforo, Martin,Daly, John J.
, p. 6577 - 6580 (2007/10/02)
The α-(2-arylhydrazino)-esters 1 react with i-propylmagnesium iodide to furnish 2-aryl-1,2-diazetidin-3-ones 2, which in turn undergo ring-opening with methyllithium affording α-(2-arylhydrazino)-ketones 3.
