Check Digit Verification of cas no
The CAS Registry Mumber 1637-52-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1637-52:
(6*1)+(5*6)+(4*3)+(3*7)+(2*5)+(1*2)=81
81 % 10 = 1
So 1637-52-1 is a valid CAS Registry Number.

experimental part, p. 3546 - 3548 (2012/02/02)
4-Pyridiniumaldoxime and 3-pyridiniumaldoxime are synthesized by the treatment of 4- and 3-pyridinecarboxaldehydes with hydroxylamine hydrochloride, respectively. Methyl triflate salts were obtained by the treatment of methyl triflate with corresponding 4-pyridiniumaldoxime and 4-pyridinecarboxaldehyde O-propragyloxime. The reactions of 4-pyridiniumaldoxime and 3-pyridiniumaldoxime with 3-bromo-l-trimethylsilyl-l-propyne yielded the corresponding pyridinecarboxaldehyde O-propragyloximes. The structures of these products were determined by 1'H, 13C NMR data and X-ray structural analysis.
