Check Digit Verification of cas no
The CAS Registry Mumber 122203-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,2,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122203-48:
(8*1)+(7*2)+(6*2)+(5*2)+(4*0)+(3*3)+(2*4)+(1*8)=69
69 % 10 = 9
So 122203-48-9 is a valid CAS Registry Number.

β-Cleavage of Bis(homoallylic) Potassium Alkoxides. Synthesis of γ-Damascone
Snowden, Roger L.,Linder, Simon M.
, p. 1587 - 1597 (2007/10/02)
Starting from the γ-lactone cis-1, two new syntheses of γ-damascone ((E)-4) are described.In both syntheses, the key step involves the β-cleavage of a bis(homoallylic)potassium alkoxide, viz. the transformation of 3a to 20 and (E/Z)-4, and the conversion
