276690-21-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 276690-21-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,6,6,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 276690-21:
(8*2)+(7*7)+(6*6)+(5*6)+(4*9)+(3*0)+(2*2)+(1*1)=172
172 % 10 = 2
So 276690-21-2 is a valid CAS Registry Number.

Enders, Dieter,Geibel, Gunter,Osborne, Simon
, p. 1302 - 1309 (2007/10/03)
Stigmatellin A (1) isolated from the myxobacterium Stigmatella aurantiaca is a powerful inhibitor of electron transport in mitochondria and chloroplasts. The first highly diastereo- and enantioselective total synthesis of this important natural product is
