Check Digit Verification of cas no

The CAS Registry Mumber 35490-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,9 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 35490-51:
(7*3)+(6*5)+(5*4)+(4*9)+(3*0)+(2*5)+(1*1)=118
118 % 10 = 8
So 35490-51-8 is a valid CAS Registry Number.

Dissolving Metal Reduction of Esters to Alkanes. A Method for the Deoxygenation of Alcohols

Barrett, Anthony G. M.,Godfrey, Christopher R. A.,Hollinshead, David M.,Prokopiou, Panayiotis A.,Barton, Derek H. R.,et al.

, p. 1501 - 1509 (2007/10/02)

Divers carboxylic esters have been reduced with dissolving Group 1A metals.Using lithium in ethylamine, sterically hindered esters (RCO2R') were deoxygenated giving the alkane (R'H) whereas non-hindered esters regenerated the parent alcohol (R'OH).This permitted the selective deoxygenation of diesters.Conversely, potassium-sodium eutectic solubilised with 18-crown-6 in t-butylamine and tetrahydrofuran (THF) efficiently deoxygenated both hindered and non-hindered esters.In the absence of nucleophiles at ambient temperture the principal reaction of carboxylic ester radical anions was deoxygenation.
