13687-98-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13687-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,8 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13687-98:
(7*1)+(6*3)+(5*6)+(4*8)+(3*7)+(2*9)+(1*8)=134
134 % 10 = 4
So 13687-98-4 is a valid CAS Registry Number.

CHEMISTRY OF ENOL ETHERS. SYNTHESIS OF UNSATURATED ALDEHYDO ACIDS AND THEIR DERIVATIVES - SYNTHONS FOR RETINOIDS

Makin, S. M.,Dobretsova, E. K.,Shavrygina, O. A.,Arshava, B. M.

, p. 445 - 448 (2007/10/02)

The reaction of 2-ethoxy-6-ethoxycarbonyl-5,6-dihydro-2H-pyrans with acidic reagents led to the synthesis of the esters of unsubstituted and methyl-substituted 2-hydroxy-6-oxo-4-hexenoic acids and 6-oxo-2E,4E-hexadienoic acids, which can be used in the synthesis of retinoids and their analogs.The initial 2-ethoxy-6-ethoxycarbonyl-5,6-dihydro-2H-pyrans were obtained by the diene condensation of ethyl glyoxylate with 1-ethoxy-1,3-dienes.
