Check Digit Verification of cas no

The CAS Registry Mumber 1238149-87-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,8,1,4 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1238149-87:
(9*1)+(8*2)+(7*3)+(6*8)+(5*1)+(4*4)+(3*9)+(2*8)+(1*7)=165
165 % 10 = 5
So 1238149-87-5 is a valid CAS Registry Number.

Diselenide- and disulfide-mediated synthesis of isocoumarins

Shahzad, Sohail A.,Venin, Claire,Wirth, Thomas

, p. 3465 - 3472 (2010)

Cyclizations of stilbenecarboxylic acids to the corresponding isocoumarin derivatives using diselenide or disulfide reagents have been developed. By employing bis(triflouroacetoxy)iodobenzene as oxidant for the 6-endo-trig cyclizations a variety of dihydroisocoumarins have been prepared in good yields. This method is capable of forming isocoumarins and dihydroisocoumarin derivatives by a cyclization-elimination route.
