Check Digit Verification of cas no

The CAS Registry Mumber 1869-76-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,6 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1869-76:
(6*1)+(5*8)+(4*6)+(3*9)+(2*7)+(1*6)=117
117 % 10 = 7
So 1869-76-7 is a valid CAS Registry Number.

Visible-Light-Promoted [5 + 1] Annulation Initiated by Electron-Donor-Acceptor Complexes: Synthesis of Perfluoroalkyl-s-Triazines

Wang, Rui,Wang, Lili,Xu, Qin,Ren, Bao-Yi,Liang, Fushun

supporting information, (2019/05/07)

A visible-light-promoted electron-donor-acceptor (EDA) complex-initiated [5 + 1] annulation between biguanides and perfluoroalkyl halides for the construction of perfluoroalkyl-s-triazines has been developed. It was found that both visible light and dioxygen in the air are favorable for the reaction. A radical-polar crossover mechanism was proposed, in which sequential SET, radical combination, HF elimination, electrocyclization, and aromatization are involved.

Conversion of biguanides into substituted s triazines assayable by GC or mass fragmentography

Alkalay,Volk,Bartlett

, p. 525 - 529 (2007/10/06)

Substituted s triazines were prepared by the treatment of biguanides with various organic acid anhydrides. This reaction permits the ready conversion of the hypoglycemic drugs, phenformin, buformin, and metformin and of other analogous biguanides into compounds suitable for GC and mass fragmentographic determination with a high degree of sensitivity. Mass spectral data and Kovats retention indexes are presented for all s triazines prepared for this study.
