Check Digit Verification of cas no

The CAS Registry Mumber 138536-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,3 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138536-48:
(8*1)+(7*3)+(6*8)+(5*5)+(4*3)+(3*6)+(2*4)+(1*8)=148
148 % 10 = 8
So 138536-48-8 is a valid CAS Registry Number.

Novel Cyclization by Stannyl Anion Generated from Me3SiSnBu3 and F(1-). The Application to the Natural Product Synthesis

Mori, Miwako,Isono, Naohiro,Kaneta, Naotake,Shibasaki, Masakatsu

, p. 2972 - 2976 (2007/10/02)

Stannyl anion, generated from Me3SiSnBu3 and (Et2N)3S(1+)*TMSF2(1-) (TASF) or CsF in DMF, was quite effective for generation of an aryl or vinyl anion, which reacted with a carbonyl group intramolecularly to provide the useful cyclized product in good yield.

, p. 255 - 260 (2007/10/02)

A metal free stannyl anion generated from Me3SiSBu3 and R4NX in DMF reacted with an aryl halide bearing carbonyl group to produce an aryl anion via the so-called halogen-metal exchange process, which reacted with a carbonyl group to afford a cyclized product in good yield.
