145125-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145125-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,1,2 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145125-20:
(8*1)+(7*4)+(6*5)+(5*1)+(4*2)+(3*5)+(2*2)+(1*0)=98
98 % 10 = 8
So 145125-20-8 is a valid CAS Registry Number.

An efficient procedure for the regioselective monoprotection of 1,2-diols
Barton,Zhu
, p. 8337 - 8346 (2007/10/02)
Nucleophilic ring opening of isopropylidende ketals by trimethylaluminium is described. This reagent offers a new method for selective monoprotection of 1,2-diols. The regioselectivity of this reaction was studied with simple diols and with carbohydrates.
