Check Digit Verification of cas no

The CAS Registry Mumber 865853-20-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,8,5 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 865853-20:
(8*8)+(7*6)+(6*5)+(5*8)+(4*5)+(3*3)+(2*2)+(1*0)=209
209 % 10 = 9
So 865853-20-9 is a valid CAS Registry Number.

Improved synthesis of quinine alkaloids with the Teoc protective group

Igarashi, Junji,Kobayashi, Yuichi

, p. 6381 - 6384 (2005)

TeocCl (Teoc: C(O)O(CH2)2TMS) generated in situ was conveniently used for trans-protection of the N-Bn piperidine intermediate to N-Teoc piperidine. Later, deprotection of the Teoc group and the subsequent quinuclidine ring formation was achieved with CsF in a domino fashion to afford the quinine alkaloids.
