Check Digit Verification of cas no

The CAS Registry Mumber 90559-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,5,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90559-99:
(7*9)+(6*0)+(5*5)+(4*5)+(3*9)+(2*9)+(1*9)=162
162 % 10 = 2
So 90559-99-2 is a valid CAS Registry Number.

supporting information; experimental part, p. 3627 - 3629 (2012/09/22)

A facile one-pot sequential three-component route to 2,4-diaminothiazoles is reported. The new approach employs the mildest reaction conditions and commercially available reagents to generate diverse 2-alkyl/arylamino-4-amino-5- aroyl/heteroylthiazoles in short reaction times, good yield, and purity.
