179871-71-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 179871-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,8,7 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 179871-71:
(8*1)+(7*7)+(6*9)+(5*8)+(4*7)+(3*1)+(2*7)+(1*1)=197
197 % 10 = 7
So 179871-71-7 is a valid CAS Registry Number.

, p. 1223 - 1228 (2007/10/03)
An efficient total synthesis of (±)-gericudranin A is described. Trihydroxyacetophenone was converted to (±)-gericudranin A in seven steps via sequential protection, aldol condensation, epoxidation, cationic cyclization, regioselective C-benzylation and d
