Check Digit Verification of cas no
The CAS Registry Mumber 19956-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,5 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19956-97:
(7*1)+(6*9)+(5*9)+(4*5)+(3*6)+(2*9)+(1*7)=169
169 % 10 = 9
So 19956-97-9 is a valid CAS Registry Number.

supporting information; experimental part, p. 12203 - 12205 (2010/10/20)
A Pd(II)-catalyzed C-H activation/C-O cyclization reaction directed by a proximate hydroxyl group has been developed. This reaction provides a new method for constructing dihydrobenzofurans, including spirocyclic analogues, a process that is potentially a
