27267-38-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27267-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,2,6 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27267-38:
(7*2)+(6*7)+(5*2)+(4*6)+(3*7)+(2*3)+(1*8)=125
125 % 10 = 5
So 27267-38-5 is a valid CAS Registry Number.

NEW SYNTHETIC METHOD OF (Z)-4-ALKENOIC ACIDS USING RING-OPENING REACTION OF (Z)-4-HEXENOLIDE WITH ORGANOCOPPER REAGENT
Fujisawa, Tamotsu,Umezu, Kazuto,Kawashima, Masatoshi
, p. 1795 - 1798 (2007/10/02)
(Z)-4-Hexenolide reacted regioselectively with diorganocuprates to give (Z)-4-alkenoic acids in high yields.Synthetic utility was demonstrated by the convenient synthesis of cis-jasmone.
