Check Digit Verification of cas no

The CAS Registry Mumber 552289-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,2,8 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 552289-41:
(8*5)+(7*5)+(6*2)+(5*2)+(4*8)+(3*9)+(2*4)+(1*1)=165
165 % 10 = 5
So 552289-41-5 is a valid CAS Registry Number.

Enantioselective total synthesis of briarellins E and F: The first total syntheses of briarellin diterpenes

Corminboeuf, Olivier,Overman, Larry E.,Pennington, Lewis D.

, p. 6650 - 6652 (2003)

Enantioselective total syntheses of briarellin E (4) and briarellin F (5) have been achieved starting with (S)-(+)-carvone and (S)-(-)-glycidol. These total syntheses are the first of briarellin diterpenes. The central step in these syntheses is acid-prom
