Check Digit Verification of cas no

The CAS Registry Mumber 749888-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,8,8 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 749888-05:
(8*7)+(7*4)+(6*9)+(5*8)+(4*8)+(3*8)+(2*0)+(1*5)=239
239 % 10 = 9
So 749888-05-9 is a valid CAS Registry Number.

An efficient synthesis of α-branched enones

Kummer, David A.,Brenneman, Jehrod B.,Martin, Stephen F.

, p. 1431 - 1433 (2007/10/03)

A new method for preparing α-branched enones from carboxylic acid derivatives is reported. The procedure commenced by the reaction of N,O-dimethylamides with a masked acyl anion equivalent, followed by the addition of (trimethylsilyl-methyl)cerium dichloride to give intermediates that undergo Lewis acid mediated olefination to produce enol ethers that are then hydrolyzed to afford simple α-branched enones in high overall yields.
