Check Digit Verification of cas no

The CAS Registry Mumber 1242072-86-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,0,7 and 2 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1242072-86:
(9*1)+(8*2)+(7*4)+(6*2)+(5*0)+(4*7)+(3*2)+(2*8)+(1*6)=121
121 % 10 = 1
So 1242072-86-1 is a valid CAS Registry Number.

Bronsted acid catalyzed cyclization of propargylic alcohols with thioamides. Facile synthesis of Di- and trisubstituted thiazoles

Zhang, Xiaoxiang,Teo, Wan Teng,Sally,Chan, Philip Wai Hong

supporting information; experimental part, p. 6290 - 6293 (2010/11/18)

Figure presented. A general and efficient method to prepare 2,4-di- and trisubstituted thiazoles via p-TsOH·H2O-catalyzed cyclization of trisubstituted propargylic alcohols with thioamides is described. The reaction was accomplished in moderate to excellent product yields under mild conditions that did not require the exclusion of air and moisture and offers an operationally simplistic and convenient route to this synthetically useful aromatic heterocycle.
