Check Digit Verification of cas no

The CAS Registry Mumber 4751-25-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,5 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4751-25:
(6*4)+(5*7)+(4*5)+(3*1)+(2*2)+(1*5)=91
91 % 10 = 1
So 4751-25-1 is a valid CAS Registry Number.

The structure of benzimidazole cyanine dyes, their spectroscopy and their performance in photographic emulsions

Peng, Zheng-Hong,Geise,Zhou, Xiang-Feng,Peng, Bi-Xian,Carleer,Dommisse

, p. 27 - 33 (1997)

The multi-step synthesis of two benzimidazole trimethine cyanines as possible green sensitizing dyes (Gs3-1, Gs3-2) is reported. Compounds were characterized from UV-Vis, mass spectroscopic and NMR data. The charge density distributions of the two compounds, calculated using the semi-empirical MOPAC 93 package, are in agreement with assignments in NMR spectroscopy. Sensitizing properties of the cyanine dyes were evaluated in actual photographic T-grain emulsions. VCH Verlagsgescllschaft mbH, 1997.
