Check Digit Verification of cas no

The CAS Registry Mumber 315681-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,5,6,8 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 315681-66:
(8*3)+(7*1)+(6*5)+(5*6)+(4*8)+(3*1)+(2*6)+(1*6)=144
144 % 10 = 4
So 315681-66-4 is a valid CAS Registry Number.

Design and synthesis of a novel water soluble benzotetrazepinone

Dumont-Hornebeck, Beatrice,Strube, Yi Ning,Vasilescu, Daniela,Jean-Claude, Bertrand Jacques

, p. 2325 - 2327 (2007/10/03)

In order to confer water solubility to the benzotetrazepinone ring system, the synthesis of 12 was undertaken. The design and synthesis of 12 were based upon previously established structural requirements for the stability of the 1,2,3,5-tetrazepin-4-one ring system. Tetrazepinone 12 was extremely water soluble and was 10-fold more potent than its imidazo-1,2,3,5-tetrazin-4-one counterpart 1a, against the human MCF-7 breast cancer cell line.
