Check Digit Verification of cas no

The CAS Registry Mumber 1259388-11-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,3,8 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1259388-11:
(9*1)+(8*2)+(7*5)+(6*9)+(5*3)+(4*8)+(3*8)+(2*1)+(1*1)=188
188 % 10 = 8
So 1259388-11-8 is a valid CAS Registry Number.

Zinc(II)-catalyzed Mannich-type reactions of hydrazones with difluoroenoxysilane and its application in the synthesis of optically active 2,2-difluoro-3-oxo-benzohydrazide

Yuan, Zhiliang,Wei, Yin,Shi, Min

experimental part, p. 1709 - 1716 (2011/07/07)

With the catalysis of Zn(OTf)2, Mannich-type reactions of various aromatic hydrazones 1 with difluoroenoxysilane 2 proceeded smoothly to produce 2,2-difluoro-3-oxo-benzohydrazides in 27%-78% yields in THF or DCM under mild conditions. An unexpe
