Check Digit Verification of cas no
The CAS Registry Mumber 187964-68-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,6 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 187964-68:
(8*1)+(7*8)+(6*7)+(5*9)+(4*6)+(3*4)+(2*6)+(1*8)=207
207 % 10 = 7
So 187964-68-7 is a valid CAS Registry Number.

Generation and Reactivity of N,N-Dimethylaminobenzotriazolylcarbene a New Nucleophilic Carbene
Katritzky, Alan R.,Cheng, Dai,Leeming, Peter,Ghiviriga, Ion,Hartshorn, Chris M.,Steel, Peter J.
, p. 1935 - 1941 (1996)
N,N-Dimethylaminobenzotriazolylcarbene (5) reacted with phenyl isocyanate in a [1+2+2] cycloaddition and then with nucleophiles to generate various hydantoins 10 in a one-pot procedure. It was also found that this novel carbene reacted with trans-dibenzoylethylene (11) in a [1+4] cycloaddition, generating 2-dimethylamino-3-benzoyl-5-pbenylfuran (13) and 2-phenyl-3-[benzotriazol-1-y1]-4-benzoylfuran (14) whose structures were confirmed by 1H-13C long range correlations as well as the structure of furan 14 being confirmed by X-ray crystallography.
