Check Digit Verification of cas no

The CAS Registry Mumber 1057691-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,6,9 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1057691-99:
(9*1)+(8*0)+(7*5)+(6*7)+(5*6)+(4*9)+(3*1)+(2*9)+(1*9)=182
182 % 10 = 2
So 1057691-99-2 is a valid CAS Registry Number.

2,2,3-Tribromopropanal as a versatile reagent in the skraup-type synthesis of 3-bromoquinolin-6-ols

Lamberth, Clemens,Kessabi, Fiona Murphy,Beaudegnies, Renaud,Quaranta, Laura,Trah, Stephan,Berthon, Guillaume,Cederbaum, Fredrik,Vettiger, Thomas,Prasanna

, p. 858 - 862 (2014)

2,2,3-Tribromopropanal, a reagent which almost became forgotten in the chemical literature after its first application in the 1950s, is used for the one-step transformation of diversely substituted 4-nitro- and 4-methoxyanilines into 3-bromo-6-nitroquinolines and 3-bromo-6-methoxyquinolines. These intermediates are then converted, in one further step, into 3-bromoquinolin-6- ols, which may carry additional substituents at positions 7 and 8. Georg Thieme Verlag Stuttgart New York.
