Check Digit Verification of cas no

The CAS Registry Mumber 143536-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,3 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143536-90:
(8*1)+(7*4)+(6*3)+(5*5)+(4*3)+(3*6)+(2*9)+(1*0)=127
127 % 10 = 7
So 143536-90-7 is a valid CAS Registry Number.

The chemistry of taxanes: Unexpected rearrangement of baccatin III during chemoselective debenzoylation with Bu3SnOMe/LiCl

Farina, Vittorio,Huang, Stella

, p. 3979 - 3982 (1992)

Chemoselective debenzoylation of 7,13-diacetyl baccatin III was achieved with tributyltin methoxide in NMP in the presence of lithium chloride as an activating agent. Surprisingly, the debenzoylation reaction was followed by rapid intramolecular cleavage of the oxetane ring to produce a novel taxane structure featuring a tetrahydrofuran ring.
