Check Digit Verification of cas no

The CAS Registry Mumber 1228105-50-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,1,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1228105-50:
(9*1)+(8*2)+(7*2)+(6*8)+(5*1)+(4*0)+(3*5)+(2*5)+(1*0)=117
117 % 10 = 7
So 1228105-50-7 is a valid CAS Registry Number.

Sodium borohydride-mediated transesterification

Sereda, Grigoriy,Pothula, Swetha,Dreessen, James

, p. 1312 - 1321 (2010)

In the presence of sodium borohydride, esters react with alcohols with formation of the corresponding esters. The reaction is sensitive to the solvent, structure of the ester, and is often concurrent with reduction. Thioesters containing an ester group can be selectively cleaved by the reagent. Both esters and thioesters attached to solid support are resistant toward sodium borohydride. The in situ prepared sodium tetraalkoxyborate is introduced as an efficient reagent and catalyst for transesterification.
