877775-43-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877775-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,7,7 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 877775-43:
(8*8)+(7*7)+(6*7)+(5*7)+(4*7)+(3*5)+(2*4)+(1*3)=244
244 % 10 = 4
So 877775-43-4 is a valid CAS Registry Number.

Krohn, Karsten,Diederichs, Jan,Riaz, Muhammad
, p. 1223 - 1230 (2007/10/03)
The sterically congested 1,2,3-substituted 3′-dealkyl mumbaistatin derivatives 16, 20, and 21 were prepared for the first time by base-catalyzed cyclization of the 2,3-bis-substituted naphthoquinone precursor 11 followed by bromine mediated photooxidation
