68690-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68690-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,6,9 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 68690-45:
(7*6)+(6*8)+(5*6)+(4*9)+(3*0)+(2*4)+(1*5)=169
169 % 10 = 9
So 68690-45-9 is a valid CAS Registry Number.

, p. 8162 - 8173 (2014/01/06)

Polyprenols, a universal class of glycan-carrier lipids, play important roles in glycan biosynthesis in wide variety of living organisms. The chemical synthesis of natural polyisoprenols such as undecaprenol and dolichols, and even more so the synthesis o

Stereo- and regioselective synthesis of squalene tetraepoxide

Tong, Rongbiao,Boone, Matthew A.,McDonald, Frank E.

experimental part, p. 8407 - 8409 (2010/02/17)

(Chemical Equation Presented) Squalene tetraepoxide, a putative biosynthetic precursor to a variety of oxacyclic triterpenoid natural products, has been efficiently synthesized by anionic coupling of two farnesol-derived diepoxides, which have arisen from
