117607-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 117607-48-4 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 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 117607-48:
(8*1)+(7*1)+(6*7)+(5*6)+(4*0)+(3*7)+(2*4)+(1*8)=124
124 % 10 = 4
So 117607-48-4 is a valid CAS Registry Number.

Intramolecular addition reactions of functionalized arylcarbenes to double bonds
Kirmse, Wolfgang,H?mberger, Günter
, p. 3925 - 3934 (2007/10/02)
Arylcarbenes with unsaturated ortho substituents (vinyloxy, 1-propenyloxy, allyl, 2-butenyl, 2,4-pentadienyl) were generated in methanol by photolysis of diazo precursors. Intermolecular OH insertion was found to compete with intramolecular addition to th
