Check Digit Verification of cas no

The CAS Registry Mumber 187347-94-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,3,4 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 187347-94:
(8*1)+(7*8)+(6*7)+(5*3)+(4*4)+(3*7)+(2*9)+(1*4)=180
180 % 10 = 0
So 187347-94-0 is a valid CAS Registry Number.

Efficient microwave access to polysubstituted amidines from imidoylbenzotriazoles

Katritzky, Alan R.,Cai, Chunming,Singh, Sandeep K.

, p. 3375 - 3380 (2007/10/03)

Microwave reactions of primary and secondary amines with imidoylbenzotriazoles 6a-w gave diversely substituted amidines 7a-Aa in 76-94% yields. Convenient preparations of a variety of amides 5a-Ab (87-96%) and imidoylbenzotriazoles 6a-w (56-95%) have also been developed using microwave irradiation under mild conditions and short reaction times. These results demonstrate further the advantages of microwave synthesis and introduce a new application of imidoylbenzotriazoles in the preparation of polysubstituted amidines.
