Check Digit Verification of cas no
The CAS Registry Mumber 133030-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,0,3 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133030-35:
(8*1)+(7*3)+(6*3)+(5*0)+(4*3)+(3*0)+(2*3)+(1*5)=70
70 % 10 = 0
So 133030-35-0 is a valid CAS Registry Number.

The Synthesis of Some Thiazolo- and Oxazolo-pyrimidines and Pyrimidinylureas. II
Hurst, Derek T.,Atcha, Shahid,Marshall, Kristina L.
, p. 129 - 134 (2007/10/02)
The reaction of some 5-acylaminopyrimidines, having 4-oxo groups, with phosphorus oxychloride or phosphorus pentasulfide leads to the oxazolo- or thiazolo-pyrimidines respectively.The condensation of amidinothiourea with pentane-2,4-dione leads to
