Check Digit Verification of cas no

The CAS Registry Mumber 298219-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,8,2,1 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 298219-30:
(8*2)+(7*9)+(6*8)+(5*2)+(4*1)+(3*9)+(2*3)+(1*0)=174
174 % 10 = 4
So 298219-30-4 is a valid CAS Registry Number.

One-pot, three component synthesis of thiazol-2(3H)-imines using poly(4-vinylpyridine) as an efficient reusable heterogeneous basic catalyst

Shiran, Jafar Abbasi,Yahyazadeh, Asieh,Mamaghani, Manouchehr,Yamin, Bohari M.,Shirini, Farhad

, p. 113 - 122 (2015/03/04)

Poly(4-vinylpyridine) is reported as a green, efficient and reusable basic catalyst for the synthesis of thiazol-2(3H)-imines under one-pot, three component reaction conditions. This simple method produces the products at room temperature in excellent yields (83-97%). Furthermore, this catalyst can be recovered by simple filtration and recycled up to four consecutive runs without any loss of its efficiency
