Check Digit Verification of cas no

The CAS Registry Mumber 1439902-76-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,9,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1439902-76:
(9*1)+(8*4)+(7*3)+(6*9)+(5*9)+(4*0)+(3*2)+(2*7)+(1*6)=187
187 % 10 = 7
So 1439902-76-7 is a valid CAS Registry Number.

Remote-control photocycloreversion of dithienylethene driven by strong push-pull azo chromophores

He, Yaning,Zhu, Yan,Chen, Zhen,He, Wei,Wang, Xiaogong

supporting information, p. 5556 - 5558 (2013/07/26)

In this communication, a novel photochromic molecular switch DTE-2(Azo-CN) containing both dithienylethene and push-pull azo chromophores was synthesized. The push-pull azo chromophores can significantly accelerate the ring opening of the C-C bond of DTE closed isomer when irradiated with light far away from the maximum absorption band of the DTE closed isomer.
