133627-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133627-65-3 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 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133627-65:
(8*1)+(7*3)+(6*3)+(5*6)+(4*2)+(3*7)+(2*6)+(1*5)=123

Effect of Triplet-State Sensitization on Inter- and Intramolecular 2+2 Photocycloadditions of 2,5-Cyclohexadien-1-ones
Schultz, Arthur G.,Geiss, William
, p. 3490 - 3494 (2007/10/02)
The intramolecular 2+2 photocycloadditions of 4-carbomethoxy-4-(4'-phenyl-3'-butenyl)-2,5-cyclohexadien-1-ones 5a, 5b, and 12 give 6-phenyltricyclo5,10>dec-2-en-4-ones 6 and 13 in excellent yields.In contrast to 4-(3'-butenyl)-4-carbome
