Check Digit Verification of cas no

The CAS Registry Mumber 49677-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,7 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 49677-01:
(7*4)+(6*9)+(5*6)+(4*7)+(3*7)+(2*0)+(1*1)=162
162 % 10 = 2
So 49677-01-2 is a valid CAS Registry Number.

A practical method for N-cyanation of secondary amines and sulfonamides

Hang, Zhaojun,Tong, Xiaowei,Li, Zuowa,Wang, Zhao-yan,Xue, Weihua

supporting information, (2022/02/07)

Cyanamides are an important class of molecules. This work describes a facile synthesis of disubstituted cyanamides. Here, readily accessible 1-cyano-1, 2-benziodoxol-3-(1H)-one (CBX) was applied as a stable electrophilic cyanation reagent. Diverse secondary amines were effectively cyanated. Moreover, secondary sulfonamides proved to be suitable substrates and were readily converted to N-alkyl(aryl)-N-arylsulfonyl-cyanamides, as the significant building blocks of the organic transformation.

Novel and facile transformation of N,N-disubstituted glycylamides into corresponding cyanamides by using pentavalent iodine reagents in combination with tetraethylammonium bromide

Chaudhari, Kiran H.,Mahajan, Ulhas S.,Bhalerao, Dinesh S.,Akamanchi, Krishnacharya G.

, p. 2815 - 2818 (2008/02/12)

Novel and facile transformation of N,N-disubstituted glycylamides into corresponding cyanamides using pentavalent iodine reagents and tetraethylammonium bromide is discussed. The advantages of this system are use of non toxic reagents, shorter reaction times and moderate to good yields. Georg Thieme Verlag Stuttgart.
