104992-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104992-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,9 and 2 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104992-92:
(8*1)+(7*0)+(6*4)+(5*9)+(4*9)+(3*2)+(2*9)+(1*2)=139
139 % 10 = 9
So 104992-92-9 is a valid CAS Registry Number.

New marine cembrane-type diterpenoids from the Okinawan soft coral Clavularia koellikeri
Iwashima,Matsumoto,Takahashi,Iguchi
, p. 1647 - 1652 (2000)
Seven new marine diterpenoids having a cembrane skeleton were isolated from the Okinawan soft coral Clavularia koellikeri. Their structures were determined based on the results of spectroscopic analysis and chemical conversions. Compound 1 showed cytotoxic activity against human colorectal adenocarcinoma cells (DLD-1, IC50 4.2 μg/mL) and strong growth inhibition against human T lymphocytic leukemia cells (MOLT-4, IC50 0.9 μg/mL).
