Check Digit Verification of cas no

The CAS Registry Mumber 1619972-71-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,9,7 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1619972-71:
(9*1)+(8*6)+(7*1)+(6*9)+(5*9)+(4*7)+(3*2)+(2*7)+(1*1)=212
212 % 10 = 2
So 1619972-71-2 is a valid CAS Registry Number.

Synthesis, structure and reactivity of a macrocyclic imine: Aza-[13]-macrodiolides

Ma, Jun,Vannam, Raghu,Terwilliger, Daniel W.,Peczuh, Mark W.

, p. 4255 - 4259 (2014)

The in situ synthesis and subsequent reactions of macrocylic imine 2 are reported. The imine was trapped with cyanotrimethylsilane to give α-amino nitrile aza-[13]-macrodiolides in a 1:1 ratio of diastereomers. A crystal structure of the syn α-cyano nitrile diastereomer, 7a, provided insights into the lack of selectivity in reactions of 2 relative to macrocyclic alkene 1. Reactions to functionalize the syn diastereomer 7a are also reported.
