528598-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 528598-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,5,9 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 528598-52:
(8*5)+(7*2)+(6*8)+(5*5)+(4*9)+(3*8)+(2*5)+(1*2)=199
199 % 10 = 9
So 528598-52-9 is a valid CAS Registry Number.

(Matrix presented) The first total synthesis of a new cytotoxic acetogenin, pyranicin (1), is described. Sml2-induced reductive cyclization of β-alkoxy acrylate 4 proceeded stereoselectively to give 16,20-syn-19,20-trans-THP derivative 14, whic
