Check Digit Verification of cas no

The CAS Registry Mumber 71492-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,9 and 2 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71492-85:
(7*7)+(6*1)+(5*4)+(4*9)+(3*2)+(2*8)+(1*5)=138
138 % 10 = 8
So 71492-85-8 is a valid CAS Registry Number.

Wang, Le,Shen, Wang

, p. 7625 - 7628 (1998)

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.
