1025964-13-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1025964-13-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,9,6 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1025964-13:
(9*1)+(8*0)+(7*2)+(6*5)+(5*9)+(4*6)+(3*4)+(2*1)+(1*3)=139
139 % 10 = 9
So 1025964-13-9 is a valid CAS Registry Number.

Synthesis of isocoumarins via palladium catalyzed reactions of methyl 2- (2',2'-dibromovinyl)benzoates
Wang, Le,Shen, Wang
, p. 7625 - 7628 (2007/10/03)
3-Substituted isocoumarins are synthesized in good to excellent yields via palladium catalyzed coupling of 2-(2',2'-dibromovinyl)benzoates and organostannanes. The process involves a Stille reaction, and a subsequent annulation reaction.
