885121-85-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 885121-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,1,2 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 885121-85:
(8*8)+(7*8)+(6*5)+(5*1)+(4*2)+(3*1)+(2*8)+(1*5)=187
187 % 10 = 7
So 885121-85-7 is a valid CAS Registry Number.

Total synthesis of (+)-β-himachalene
Ho, Tse-Lok,Chein, Rong-Jie
, p. 231 - 239 (2007/10/03)
An enantioselective synthesis of (+)-β-himachalene (2) was accomplished starting from (1S,2R)-1,2-epoxy-p-menth-8-ene (3) in 15 or 16 steps with an overall yield of ca. 6% (Schemes 3, 5, and 6). Key transformations include an Ireland-Claisen rearrangement, a Corey oxidative cyclization, and a ring expansion.
