Check Digit Verification of cas no

The CAS Registry Mumber 321887-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,8,8 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 321887-10:
(8*3)+(7*2)+(6*1)+(5*8)+(4*8)+(3*7)+(2*1)+(1*0)=139
139 % 10 = 9
So 321887-10-9 is a valid CAS Registry Number.

Efficient synthesis of (-)-methyl 3-epi-shikimate and methyl 3-epi-quinate by one-pot selective protection of trans-1,2-diols

Armesto,Ferrero,Fernandez,Gotor

, p. 8759 - 8762 (2000)

trans-1,2-Diol protections of shikimic and quinic acids have been achieved by in situ formation of the protecting group (2,2,3,3-tetramethoxybutane). The synthetic utility of the protected derivatives is demonstrated by the preparation of (-)-methyl 3-epi
