Check Digit Verification of cas no

The CAS Registry Mumber 681440-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,4,4 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 681440-04:
(8*6)+(7*8)+(6*1)+(5*4)+(4*4)+(3*0)+(2*0)+(1*4)=150
150 % 10 = 0
So 681440-04-0 is a valid CAS Registry Number.

ortho-anisylsulfonyl as a protecting group for secondary amines: Mild Ni0-catalyzed hydrodesulfonylation

Milburn, Robert R.,Snieckus, Victor

, p. 892 - 894 (2007/10/03)

A potentially good alternative to the tosyl group (Ts) as a protecting group for amines is N-ortho-anisylsulfonyl (Ans), which is readily cleaved under mild, Ni0-catalyzed reductive conditions (see scheme, acac = acetylacetonate). N-Anisylation of primary amines followed by alkylation and deprotection provides a route to a range of secondary amines.
