Check Digit Verification of cas no

The CAS Registry Mumber 1309856-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,8,5 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1309856-40:
(9*1)+(8*3)+(7*0)+(6*9)+(5*8)+(4*5)+(3*6)+(2*4)+(1*0)=173
173 % 10 = 3
So 1309856-40-3 is a valid CAS Registry Number.

A general palladium-catalyzed carbonylative synthesis of chromenones from salicylic aldehydes and benzyl chlorides

Wu, Xiao-Feng,Wu, Lipeng,Jackstell, Ralf,Neumann, Helfried,Beller, Matthias

, p. 12245 - 12248 (2013)

Cute CO! An interesting and straightforward procedure for the carbonylative synthesis of chromenones from readily available salicylic aldehydes and benzyl chlorides has been developed (see scheme; DPPP=1,3-bis(diphenylphosphino) propane). In the presence of a palladium catalyst, various coumarins were produced in good to excellent yields. Copyright
