553665-13-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 553665-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,3,6,6 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 553665-13:
(8*5)+(7*5)+(6*3)+(5*6)+(4*6)+(3*5)+(2*1)+(1*3)=167
167 % 10 = 7
So 553665-13-7 is a valid CAS Registry Number.

Total synthesis of microcarpalide
Gurjar, Mukund K.,Nagaprasad, Ravi,Ramana
, p. 2873 - 2875 (2007/10/03)
A total synthesis of the natural product microcarpalide is described. Ring-closing metathesis of a dienic ester was used as the key step. Mannose was used as the chiral pool material for the construction of the olefinic-acid and a Sharpless asymmetric dih
