Check Digit Verification of cas no

The CAS Registry Mumber 100867-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,8,6 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 100867-22:
(8*1)+(7*0)+(6*0)+(5*8)+(4*6)+(3*7)+(2*2)+(1*2)=99
99 % 10 = 9
So 100867-22-9 is a valid CAS Registry Number.

Synthesis of substituted 6H-benzo[c]chromenes: A palladium promoted ring closure of diazonium tetrafluoroborates

Zhou, Jing,Huang, Liang-Zhu,Li, You-Qiang,Du, Zhen-Ting

, p. 7036 - 7039 (2013/01/15)

A highly efficient palladium-catalysed phenyl diazonium tetrafluoroborate participation of C-H activation ring closure protocol has been developed. A series of 6H-benzo[c]chromenes have been synthesized by intramolecular cyclization of ortho diazonium sal
