637002-77-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637002-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,0 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 637002-77:
(8*6)+(7*3)+(6*7)+(5*0)+(4*0)+(3*2)+(2*7)+(1*7)=138
138 % 10 = 8
So 637002-77-8 is a valid CAS Registry Number.

Enantioselective Total Synthesis of (+)-Leucascandrolide A Macrolactone
Crimmins, Michael T.,Siliphaivanh, Phieng
, p. 4641 - 4644 (2007/10/03)
(Matrix presented) The enantioselective synthesis of the (+)-leucascandrolide A macrolactone has been achieved in 20 linear steps from 1,3-propanediol. The key steps in the synthesis are a reductive cleavage of bicyclic ketal 5 to establish the C15 stereo
