Check Digit Verification of cas no

The CAS Registry Mumber 1218941-79-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,9,4 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1218941-79:
(9*1)+(8*2)+(7*1)+(6*8)+(5*9)+(4*4)+(3*1)+(2*7)+(1*9)=167
167 % 10 = 7
So 1218941-79-7 is a valid CAS Registry Number.

Regioselective enzymatic acylation of troxerutin in nonaqueous medium

Xiao, Yong Mei,Mao, Pu,Zhao, Zhen,Yang, Liang Ru,Lin, Xian Fu

scheme or table, p. 59 - 62 (2010/11/16)

A series of monosubstituted troxerutin esters have been synthesized by enzyme-catalyzed regioselective acylation of troxerutin in nonaqueous medium. Using divinyl dicarboxylates (CH2{double bond, long}CH{single bond}OOC{single bond}(CH2)n{single bond}COO{single bond}CH{double bond, long}CH2, n = 2, 3, 4, 7, 8, 11) featuring different chain length as acyl donors and alkaline protease from Bacillus subtilis as catalyst, troxerutin was regioselective acylated at B' ethoxyl group. The results indicated that the regioselectivity of the enzyme-catalyzed acylation was not affected by the chain length of the acyl donor.
