Check Digit Verification of cas no
The CAS Registry Mumber 129847-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,8,4 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 129847-09:
(8*1)+(7*2)+(6*9)+(5*8)+(4*4)+(3*7)+(2*0)+(1*9)=162
162 % 10 = 2
So 129847-09-2 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
