Check Digit Verification of cas no

The CAS Registry Mumber 1313430-10-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,4,3 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1313430-10:
(9*1)+(8*3)+(7*1)+(6*3)+(5*4)+(4*3)+(3*0)+(2*1)+(1*0)=92
92 % 10 = 2
So 1313430-10-2 is a valid CAS Registry Number.

Direct sequential C-O and C-C formation via double sp2 C-H bond activations to construct 6H-benzo[c]chromen-6-ones

Sun, Chang-Liang,Liu, Jia,Wang, Yang,Zhou, Xiao,Li, Bi-Jie,Shi, Zhang-Jie

, p. 883 - 886 (2011)

A new method for the direct ortho acyloxylation of sp2 C-H bond with various carboxylic acids was developed. A novel strategy to synthesize 6H-benzo[c]chromen-6-one derivatives was designed via Pd-catalyzed double activations of adjacent spsup
