1197951-74-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197951-74-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,9,5 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1197951-74:
(9*1)+(8*1)+(7*9)+(6*7)+(5*9)+(4*5)+(3*1)+(2*7)+(1*4)=208
208 % 10 = 8
So 1197951-74-8 is a valid CAS Registry Number.

Studies on the C22-C23 aldol coupling of spirangien
Lorenz, Michael,Bluhm, Nadine,Kalesse, Markus
experimental part, p. 3061 - 3066 (2009/12/28)
The aldol reaction is one of the most powerful and versatile methods in polyketide synthesis. Nevertheless, the subtle directing effects remain very often obscure and impede complex natural products syntheses. Here, we report studies on the pivotal aldol
