Check Digit Verification of cas no

The CAS Registry Mumber 73956-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73956-65:
(7*7)+(6*3)+(5*9)+(4*5)+(3*6)+(2*6)+(1*5)=167
167 % 10 = 7
So 73956-65-7 is a valid CAS Registry Number.

β-Cleavage of Bis(homoallylic) Potassium Alkoxides. Synthesis of γ-Damascone

Snowden, Roger L.,Linder, Simon M.

, p. 1587 - 1597 (2007/10/02)

Starting from the γ-lactone cis-1, two new syntheses of γ-damascone ((E)-4) are described.In both syntheses, the key step involves the β-cleavage of a bis(homoallylic)potassium alkoxide, viz. the transformation of 3a to 20 and (E/Z)-4, and the conversion

Photochemishe Reactionen. 130 Mitteilung. Zur Photochemie von 5,6-Epoxy-1,3-dienen: Der Einfluss eines 7-Hydroxysubstituenten auf die Carbenbildung

Weck, Guy de,Nakamura, Norio,Tsutsumi, Kentaro,Wolf, Hans Richard,Frei, Bruno,Jeger, Oskar

, p. 2236 - 2251 (2007/10/02)

On singlet excitation (λ=254 nm) in MeCN the hydroxy-epoxydiene (E)-4 undergoes photocleavage to the carbene intermediates d and e as main processes.The carbene d, showing behaviour typical of vinyl carbenes, undergoes addition to the adjacent double bond
