Check Digit Verification of cas no

The CAS Registry Mumber 1242316-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,3,1 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1242316-85:
(9*1)+(8*2)+(7*4)+(6*2)+(5*3)+(4*1)+(3*6)+(2*8)+(1*5)=123
123 % 10 = 3
So 1242316-85-3 is a valid CAS Registry Number.

Efficient synthesis of a new type of baylis-hillman adducts and their stereoselective bromination

Zhong, Weihui,Jiang, Lingbo,Guo, Baoming,Wu, Yaotiao,Hong, Lingjuan,Chen, Yanhui

, p. 2441 - 2456 (2010)

A new type of Baylis-Hillman adducts derived from chlorovinyl aldehydes were prepared via Vilsmeier reaction of ketones with a bis(trichloromethyl) carbonate (BTC)/DMF system to construct chlorovinyl aldehydes, followed by sonochemical Baylis-Hillman reaction under solvent-free conditions. The stereoselective bromination of these new compounds with a Br2-Ph3P system has been achieved efficiently with good to excellent yields under mild conditions.
