Check Digit Verification of cas no

The CAS Registry Mumber 552838-53-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,2,8,3 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 552838-53:
(8*5)+(7*5)+(6*2)+(5*8)+(4*3)+(3*8)+(2*5)+(1*3)=176
176 % 10 = 6
So 552838-53-6 is a valid CAS Registry Number.

Preparation of highly substituted (β-acylamino)acrylates via iron-catalyzed alkoxycarbonylation of N-vinylacetamides with carbazates

Ding, Ran,Zhang, Qiu-Chi,Xu, Yun-He,Loh, Teck-Peng

supporting information, p. 11661 - 11664 (2015/05/20)

An efficient iron(ii)-catalyzed alkoxycarbonylation reaction between N-vinylacetamides and carbazates is reported. The corresponding useful highly substituted (β-acylamino)acrylates could be obtained in reasonable to good yields and stereoselectivity under mild reaction conditions. This journal is
