Check Digit Verification of cas no

The CAS Registry Mumber 402945-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,9,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 402945-32:
(8*4)+(7*0)+(6*2)+(5*9)+(4*4)+(3*5)+(2*3)+(1*2)=128
128 % 10 = 8
So 402945-32-8 is a valid CAS Registry Number.

Aryliodoazide synthons: A different approach for diversified synthesis of 2-aminothiazole, 1,3-thiazole, and 1,3-selenazole scaffolds

Majnooni, Sahar,Duffield, Joseph,Price, Jessica,Khosropour, Ahmad Reza,Zali-Boeini, Hassan,Beyzavi, M. Hassan

, p. 516 - 521 (2019)

Several straightforward and practical processes have been established for the construction of 2-aminothiazoles, 1,3-thiazoles and 1,3-selenazoles from aryliodoazides. These strategies successfully proceed with a wide spectrum of substituted thioamides and its derivatives producing the resulting five-membered heterocycles obtained in satisfactory yields. The unique features of these protocols are operational simplicity and highly functional group tolerance, which make them convenient and practical routes for the preparation of various libraries of 2-aminothiazoles, 1,3-thiazoles, and 1,3-selenazoles.
