Check Digit Verification of cas no

The CAS Registry Mumber 139547-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139547-74:
(8*1)+(7*3)+(6*9)+(5*5)+(4*4)+(3*7)+(2*7)+(1*4)=163
163 % 10 = 3
So 139547-74-3 is a valid CAS Registry Number.

A New Route to 1,3-Benzoxazepines and 1,3-Benzodiazepines via Intramolecular Aza-Wittig Reaction

Kurita, Jyoji,Iwata, Takao,Yasuike, Shuji,Tsuchiya, Takashi

, p. 81 - 82 (1992)

The reaction of triphenylphosphine with the o-acyloxy-5 and o-acylamino-azidocinnamates 9, prepared from salicylaldehyde and o-aminobenzaldehyde, results in ring closure to give the 1,3-benzoxazepines 7 and 1,3-benzodiazepines 12, via the intramolecular a
