Check Digit Verification of cas no

The CAS Registry Mumber 1438272-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,2,7 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1438272-75:
(9*1)+(8*4)+(7*3)+(6*8)+(5*2)+(4*7)+(3*2)+(2*7)+(1*5)=173
173 % 10 = 3
So 1438272-75-3 is a valid CAS Registry Number.

supporting information, p. 7048 - 7052 (2013/02/21)

A simple and scalable procedure to introduce alcohols selectively at the 3-position of 3,4,5-trifluoroaniline is described. The procedure uses powdered NaOH as base and catalytic 15-crown-5 in refluxing toluene with a Dean-Stark trap. A short exploration of other nucleophiles and fluoroaryl electrophiles is also described.
