Check Digit Verification of cas no

The CAS Registry Mumber 22503-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,0 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22503-12:
(7*2)+(6*2)+(5*5)+(4*0)+(3*3)+(2*1)+(1*2)=64
64 % 10 = 4
So 22503-12-4 is a valid CAS Registry Number.

Synthesis of ortho-phenylenebis(guanidine) derivatives with potential chirality

Fukuzumi, Masahiro,Nakanishi, Waka,Ishikawa, Tsutomu,Kumamoto, Takuya

, p. 1453 - 1468 (2015/02/19)

We report the synthesis and potential chirality of ortho-phenylenebisguanidines (BGs) with substituents at C(3) and C(6). Guanidinylation of 3,6-disubstituted benzene-1,2-diamines with 2-chloro-4,5-dihydro-1,3-dimethyl-1H-imidazolium chloride gave the corresponding BGs. X-Ray crystallography showed that the two guanidine moieties occupy different faces of the benzene ring, creating potential chirality, although optical resolution of tBu-substituted BG by chiral HPLC failed. However, a methylated acyclic bisguanidinium salt (BGms) was obtained as a chiral crystal with a space group of P212121.
