Check Digit Verification of cas no

The CAS Registry Mumber 25992-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,9 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25992-30:
(7*2)+(6*5)+(5*9)+(4*9)+(3*2)+(2*3)+(1*0)=137
137 % 10 = 7
So 25992-30-7 is a valid CAS Registry Number.

East Indian Sandalwood Oil. 2. Stereoselective Synthesis of (+/-)-Epi-β-santalene and (+/-)-Epi-β-santalol

Christenson, Philip A.,Willis, Brian J.

, p. 3068 - 3072 (2007/10/02)

Acid-catalyzed rearrangement of γ-lactone 6 in the presence of acetonitrile provides a mixture of amide acids, which are readily separated as their ethyl esters 18-20.The major product 18, when subjected to fragmentation, provides esters 21 and 22 (92percent and 8percent, respectively).The structure of 21 has been confirmed by its conversion, via aldehyde 23, to (+/-)-epi-β-santalene (8).Similarly, the structure of 22 has been confirmed by its conversion to (+/-)-α-santalene (3). (+/-)-Epi-cis-β-santalol (9), (+/-)-epi-trans-β-santalol (10), and (+/-)-dihydroepi-β-santalol (11) have also been prepared via aldehyd 23.
