Check Digit Verification of cas no

The CAS Registry Mumber 1427201-87-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,0 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1427201-87:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*0)+(3*1)+(2*8)+(1*7)=133
133 % 10 = 3
So 1427201-87-3 is a valid CAS Registry Number.

Regioselective polymethylation of α-(1 → 4)-linked mannopyranose oligosaccharides

Xia, Li,Lowary, Todd L.

, p. 2863 - 2880 (2013/07/04)

An approach has been developed of the regioselective methylation of α-(1 → 4)-linked mannopyranose oligosaccharides via a four-step methodology. The key reaction involved n-Bu2SnCl2-mediated activation of cis-diols. By tuning protecting groups on the substrates, multiple cis-diols in the substrates were functionalized in a consistent and regioselective manner. Using optimized substrates and reaction conditions, regioselective methylation of di-, tri-, and tetrasaccharide substrates proceeded in isolated yields per cis-diol of 95, 88 and 79%, respectively. The methodology was also applied to functionalize trans-diols in α-cyclodextrin.
