Check Digit Verification of cas no

The CAS Registry Mumber 1248412-52-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,4,1 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1248412-52:
(9*1)+(8*2)+(7*4)+(6*8)+(5*4)+(4*1)+(3*2)+(2*5)+(1*2)=143
143 % 10 = 3
So 1248412-52-3 is a valid CAS Registry Number.

A simple method for the synthesis of functionalized 6-aryl-6H-dibenzo[b,d] pyran derivatives from 3-nitro-2H chromenes

Li, Ping,Luo, Ling-Ling,Li, Xin-Sheng,Xie, Jian-Wu

experimental part, p. 7590 - 7594 (2010/12/19)

The one-pot synthesis of multi-substituted 6-aryl-6H-dibenzo[b,d]pyran derivatives was achieved via vinylogous Michael addition as the key step and domino reactions under mild reaction conditions, employing readily available α,α-dicyanoolefins and 3-nitro-2H-chromenes as substrates.
