253608-17-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253608-17-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,6,0 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 253608-17:
(8*2)+(7*5)+(6*3)+(5*6)+(4*0)+(3*8)+(2*1)+(1*7)=132
132 % 10 = 2
So 253608-17-2 is a valid CAS Registry Number.

Total synthesis of a new cytotoxic acetogenin, jimenezin, and the revised structure.
Takahashi,Maeda,Hirota,Nakata
, p. 2025 - 2028 (2008/02/11)
The first total synthesis of jimenezin was achieved by using carbohydrates as chiral building blocks, thus revising the proposed structure 1 to 2. The key steps in this synthesis include an efficient construction of the THP-THF fragments 3 and 16 through
