Check Digit Verification of cas no

The CAS Registry Mumber 853644-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,3,6,4 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 853644-88:
(8*8)+(7*5)+(6*3)+(5*6)+(4*4)+(3*4)+(2*8)+(1*8)=199
199 % 10 = 9
So 853644-88-9 is a valid CAS Registry Number.

Preparation of aryl-substituted butenolides using mucohalic acids

-

Page/Page column 9, (2008/06/13)

Methods and materials for preparing 3-aryl-2-buten-4-olides and 2,3-bisaryl-2-buten-4-olides are disclosed. The methods include reacting a mucohalic acid with a reducing agent to give a 2,3-dihalo-2-buten-4-olide, which undergoes at least one Pd catalyzed cross-coupling reaction with an arylboronic acid.
