7439-77-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7439-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,3 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7439-77:
(6*7)+(5*4)+(4*3)+(3*9)+(2*7)+(1*7)=122
122 % 10 = 2
So 7439-77-2 is a valid CAS Registry Number.

Bufospirostenin A and Bufogargarizin C, Steroids with Rearranged Skeletons from the Toad Bufo bufo gargarizans

supporting information, p. 1182 - 1186 (2017/05/05)

Bufospirostenin A (1) and bufogargarizin C (2), two novel steroids with rearranged A/B rings, were isolated from the toad Bufo bufo gargarizans. Compound 1 represents the first spirostanol found in animals. Compound 2 is an unusual bufadienolide with a cycloheptatriene B ring. Their structures were elucidated by spectroscopic analysis, single crystal X-ray diffraction analysis, and computational calculations.
