849435-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849435-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,4,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 849435-20:
(8*8)+(7*4)+(6*9)+(5*4)+(4*3)+(3*5)+(2*2)+(1*0)=197
197 % 10 = 7
So 849435-20-7 is a valid CAS Registry Number.

The first synthesis of (S)-(+)-cacalol
Tanikawa, Shin,Ono, Machiko,Akita, Hiroyuki
, p. 319 - 327 (2007/10/03)
The first synthesis of (S)-(+)-cacalol (1) was achieved by a combination of the BF3·Et2O-mediated reaction of (S)-4,5-epoxy-(2E)-pentenoate (7) with 3,4-dimethoxytoluene to give (S)-4-aryl-5-hydroxy-(2E)-pentenoate (5) and consecutiv
