137445-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137445-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,4 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 137445-61:
(8*1)+(7*3)+(6*7)+(5*4)+(4*4)+(3*5)+(2*6)+(1*1)=135
135 % 10 = 5
So 137445-61-5 is a valid CAS Registry Number.

Synthesis of (+)-dihydrocompactin and (+)-compactin via vinylsilane terminated cationic cyclization
Burke, Steven D.,Deaton, David N.
, p. 4651 - 4654 (2007/10/02)
Two enantioselective routes to the octalin diol 1 are described, featuring cationic polyene cyclization mediated by a vinylsilane terminating group and a benzenedimethanol acetal initiator. Further transformations resulting in formal and total syntheses o
