Check Digit Verification of cas no

The CAS Registry Mumber 138912-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,1 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138912-50:
(8*1)+(7*3)+(6*8)+(5*9)+(4*1)+(3*2)+(2*5)+(1*0)=142
142 % 10 = 2
So 138912-50-2 is a valid CAS Registry Number.

Neighboring Effect of a Carbonyl Group in Base-Induced Wittig-Type Rearrangements of Poly(4-nitrobenzyloxy)tropones to Bis- and Mono(α-hydroxy-4-nitrobenzyl)tropones

Yin, Bing Zhu,Mori, Akira,Takeshita, Hitoshi

, p. 3306 - 3312 (2007/10/02)

The base-catalyzed rearrangement of bis- and tris(4-nitrobenzyloxy)tropones gave (α-hydroxy-4-nitrobenzyl)tropones through a Wittig-type mechanism.Only the 4-nitrobenzyloxy group adjacent to the carbonyl group migrated.The carbonyl group played a role in
