Check Digit Verification of cas no
The CAS Registry Mumber 137255-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,5 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137255-07:
(8*1)+(7*3)+(6*7)+(5*2)+(4*5)+(3*5)+(2*0)+(1*7)=123
123 % 10 = 3
So 137255-07-3 is a valid CAS Registry Number.

Synthesis of earthy-mouldy smelling compounds - II. Ethyl α and β-fenchols
Gosselin,Joulain,Laurin,Rouessac
, p. 3151 - 3154 (2007/10/02)
Several stereoselective routes to both ethyl α- and β- fenchols 1α and 1β are discussed. Direct addition of ethyllithium to fenchone was the best route to 1α whereas obtention of 1β was achieved through the highly stereoselective retroethylnylation of a mixture of ethynyl α- and β-fenchols 4α and 4β.
