Check Digit Verification of cas no
The CAS Registry Mumber 188397-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,3,9 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188397-05:
(8*1)+(7*8)+(6*8)+(5*3)+(4*9)+(3*7)+(2*0)+(1*5)=189
189 % 10 = 9
So 188397-05-9 is a valid CAS Registry Number.

Karam, Omar,Zunino, Fabien,Chagnaut, Vincent,Jouannetaud, Marie Paule,Jacquesy, Jean Claude
, p. 1511 - 1513 (2007/10/03)
A four-step synthesis of 6-hydroxymelatonin 5, major human metabolite of melatonin 1, is reported starting from melatonin. The synthesis involves in the keys steps a regioselective Friedel-Crafts acylation followed by a Baeyer-Villiger oxidation. The overall yield is 48%.
