130518-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130518-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,5,1 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130518-97:
(8*1)+(7*3)+(6*0)+(5*5)+(4*1)+(3*8)+(2*9)+(1*7)=107
107 % 10 = 7
So 130518-97-7 is a valid CAS Registry Number.

Masked Lithium Bishomoenolates: Useful Intermediates in Organic Synthesis
Ramon, Diego J.,Yus, Miguel
, p. 3825 - 3831 (2007/10/02)
The lithiation of the chloro ketals 9 with lithium naphthalenide at -78 deg C led to the corresponding masked lithium bishomoenolates 4, which are stable species under these conditions and react with different electrophilic reagents (H2O, D2O, i-PrCOH, Ph
