Check Digit Verification of cas no

The CAS Registry Mumber 40648-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,4 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40648-44:
(7*4)+(6*0)+(5*6)+(4*4)+(3*8)+(2*4)+(1*4)=110
110 % 10 = 0
So 40648-44-0 is a valid CAS Registry Number.

Catalytic synthesis of 3-alkoxyacrylic acid esters under neat conditions

Wang, Junhua,Wang, Honglin,Ren, Hongmin

, p. 980 - 983 (2010)

Triethylamine or Ph3P (0.05 eq.) was found to catalyze the addition of alcohols to alkyl propiolates. The reaction occurred much more rapidly without solvent than in solvent. The E/Z ratio was relative to the reaction temperature. Water was fou
