Check Digit Verification of cas no
The CAS Registry Mumber 508203-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,8,2,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 508203-48:
(8*5)+(7*0)+(6*8)+(5*2)+(4*0)+(3*3)+(2*4)+(1*8)=123
123 % 10 = 3
So 508203-48-3 is a valid CAS Registry Number.

A practical and cost-efficient, one-pot conversion of aldehydes into nitriles mediated by 'activated DMSO'
Augustine, John Kallikat,Bombrun, Agnes,Atta, Rajendra Nath
scheme or table, p. 2223 - 2227 (2011/10/31)
Participation of activated DMSO in the one-pot transformation of aldehydes to nitriles has been described by reacting aldehydes with NHHHCl in DMSO in the absence of any added base or catalyst. The method is applicable to access a wide range of aromatic, heterocyclic, and aliphatic nitriles, in which only water is a byproduct. A straightforward and practical procedure is demonstrated on a multigram scale. Georg Thieme Verlag Stuttgart - New York.
