Check Digit Verification of cas no

The CAS Registry Mumber 99320-80-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99320-80:
(7*9)+(6*9)+(5*3)+(4*2)+(3*0)+(2*8)+(1*0)=156
156 % 10 = 6
So 99320-80-6 is a valid CAS Registry Number.

A new method for one-pot synthesis of aryloxyphenoxypropionate herbicides using 2,4,6-trichloro-1,3,5-triazine and (n-BU)4NI as a homogeneous catalyst

Kalhor, Mehdi,Dadras, Akbar,Mobinikhaledi, Akbar,Tajik, Hassan

experimental part, p. 833 - 836 (2012/05/04)

The one-pot reaction of halo-heterocycle, (R)-4-hydroxyphenoxy propionic acid and an alcohol, amine or sulfonamide is described as an efficient method for the synthesis of aryloxyphenoxy propionate hrerbicides by using 2,4,6-trichloro-1,3,5-triazine in the presence of (n-BU) 4NI, as a homogeneous catalyst under mild conditions. The present procedure offers several advantages, such as good yields, short reaction times and easy workup.
