136771-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136771-93-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,7 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136771-93:
(8*1)+(7*3)+(6*6)+(5*7)+(4*7)+(3*1)+(2*9)+(1*3)=152
152 % 10 = 2
So 136771-93-2 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
