149057-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149057-51-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,0,5 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 149057-51:
(8*1)+(7*4)+(6*9)+(5*0)+(4*5)+(3*7)+(2*5)+(1*1)=142
142 % 10 = 2
So 149057-51-2 is a valid CAS Registry Number.

Selective deacylation on the glucosyl moiety of octa-O-acetylsucrose by enzymic hydrolysis: Formation of 2,1',3',4',6'-penta-O-acetylsucrose
Ong,Chang,Wu,Wang
, p. 327 - 333 (2007/10/02)
Partially acetylated sucroses have been prepared by several approaches. This paper reports that octa-O-acetylsucrose was hydrolyzed by lipase OF(Candida ylindracea); it was found that deacylation occured only in the glucosyl moiety.
