Check Digit Verification of cas no

The CAS Registry Mumber 898920-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,9,2 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 898920-55:
(8*8)+(7*9)+(6*8)+(5*9)+(4*2)+(3*0)+(2*5)+(1*5)=243
243 % 10 = 3
So 898920-55-3 is a valid CAS Registry Number.

Synthesis of amino acid derivatives of hydrazones and oximes of spirodihydropyranochromen-2-ones

Veselovska,Garazd,Ogorodniychuk,Garazd,Khilya

experimental part, p. 153 - 162 (2009/04/03)

Sulfur-and nitrogen-containing derivatives of spirodihydropyranochromen-2- ones at the exocyclic oxygen atom have been synthesized. Modification of the oximes and hydrazones of the spiro-substituted pyranocoumarins with N-substituted amino acids were carried out using activated ester and symmetrical anhydride methods.
