104900-68-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104900-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,9,0 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104900-68:
(8*1)+(7*0)+(6*4)+(5*9)+(4*0)+(3*0)+(2*6)+(1*8)=97
97 % 10 = 7
So 104900-68-7 is a valid CAS Registry Number.

Total synthesis of (±)-smenospondiol by titanium(III)-mediated tandem radical cyclization
Haruo,Hasegawa,Tanaka,Takahashi
, p. 1935 - 1937 (2001)
We describe the total synthesis of (±)-smenospondiol(1). Stereoselective construction of the drimane skeleton was accomplished by titanium(III)-mediated tandem radical cyclization of epoxide 9. Non-polar solvent is essential for the success of the tandem
