133625-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133625-61-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,2 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133625-61:
(8*1)+(7*3)+(6*3)+(5*6)+(4*2)+(3*5)+(2*6)+(1*1)=113
113 % 10 = 3
So 133625-61-3 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
