140170-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 140170-22-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,7 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140170-22:
(8*1)+(7*4)+(6*0)+(5*1)+(4*7)+(3*0)+(2*2)+(1*2)=75
75 % 10 = 5
So 140170-22-5 is a valid CAS Registry Number.

Studies towards the synthesis of obtusenyne. Synthesis of the hexahydrooxonin nucleus

Curtis, Neil R.,Holmes, Andrew B.,Looney, Mark G.

, p. 671 - 674 (2007/10/02)

The advanced intermediate (the 2,3,4,7,8,9-hexahydrooxonin) 3 for the synthesis of the Laurencia oxonane natural product, obtusenyne 1 was prepared in 8 steps from the previously reported lactone 4. The key transformations were the stereoselective enolate
