187268-44-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187268-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,2,6 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187268-44:
(8*1)+(7*8)+(6*7)+(5*2)+(4*6)+(3*8)+(2*4)+(1*4)=176
176 % 10 = 6
So 187268-44-6 is a valid CAS Registry Number.

Synthesis of (E,E,E)-(1,2,3,4-13C4)-geranylgeraniol
Eis, Knut,Schmalz, Hans-Günther
, p. 202 - 206 (2007/10/03)
A synthesis of (E,E,E)-(1,2,3,4-13C4)-geranylgeraniol (2') (5 steps, ≤ 30% overall yield) is described starting from farnesol (3). The synthesis is based on the Sum/Weiler protocol, which was found to be superior after investigating
