108645-52-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108645-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 108645-52:
(8*1)+(7*0)+(6*8)+(5*6)+(4*4)+(3*5)+(2*5)+(1*2)=129
129 % 10 = 9
So 108645-52-9 is a valid CAS Registry Number.

Total synthesis of α- and β-himachalene by an intramolecular Diels-Alder approach
Liu, Hsing-Jang,Browne, Eric N. C.
, p. 601 - 608 (2007/10/02)
A total synthesis of α-himachalene (2) and β-himachalene (3) has been achived in eleven steps and in an effective overall yield of 21percent from 4,4-dimethyl-2-cyclohexanone (4).The synthesis involves keto ester 7 as a key intermediate wich is convenient
