Check Digit Verification of cas no

The CAS Registry Mumber 1248337-18-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,3,3 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1248337-18:
(9*1)+(8*2)+(7*4)+(6*8)+(5*3)+(4*3)+(3*7)+(2*1)+(1*8)=159
159 % 10 = 9
So 1248337-18-9 is a valid CAS Registry Number.

Effects of multibranching on 3-hydroxyflavone-based chromophores and the excited-state intramolecular proton transfer dynamics

Lin, Chao-Chen,Chen, Chyi-Lin,Chung, Min-Wen,Chen, Yi-Ju,Chou, Pi-Tai

, p. 10412 - 10420 (2010)

A series of one-, two-, and three-branched chromophores based on 3-hydroxyflavones (1-3) have been synthesized as the first example of multibranched chromophores demonstrating excited-state intramolecular proton transfer (ESIPT). Coupling between the 3-hy
