Check Digit Verification of cas no

The CAS Registry Mumber 188981-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,8 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188981-81:
(8*1)+(7*8)+(6*8)+(5*9)+(4*8)+(3*1)+(2*8)+(1*1)=209
209 % 10 = 9
So 188981-81-9 is a valid CAS Registry Number.

Asymmetric amino-hydroxylation of dienylsilanes. An efficient route to amino-cyclitols

Angelaud, Remy,Landais, Yannick,Schenk, Kurt

, p. 1407 - 1410 (2007/10/03)

Sharpless asymmetric amino-hydroxylation of a silyl-2,5-cyclohexadiene occurs with complete regio- and diastereocontrol. An enantioselectivity of up to 68% e.e. was also observed. An application of the methodology to the synthesis of relevant examples of amino-cyclitols is described.
