Check Digit Verification of cas no

The CAS Registry Mumber 685887-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,5,8,8 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 685887-86:
(8*6)+(7*8)+(6*5)+(5*8)+(4*8)+(3*7)+(2*8)+(1*6)=249
249 % 10 = 9
So 685887-86-9 is a valid CAS Registry Number.

Synthesis of Benzophenone-Containing Analogues of Phosphatidylcholine

Wang, Pingzhen,Blank, David H.,Spencer, Thomas A.

, p. 2693 - 2702 (2007/10/03)

As part of a collaborative study of cellular efflux of cholesterol and phospholipids, photoactivable analogues 4-8 of phosphatidylcholine (PC) having benzophenone groups in the choline moiety and at the end of the C2 and C1 alkyl chains have been synthesized. The efficient preparation via Suzuki coupling of the appropriate long-chain benzophenone-containing carboxylic acid and alcohol and their incorporation by adaptation of known approaches into the acyl- and ether-linked PC analogues 6-8 are described. Development of a method for radiolabeling these PC analogues, via hydrogenation of a double bond in modified side chains, is also described.
