Check Digit Verification of cas no

The CAS Registry Mumber 78962-35-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,6 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78962-35:
(7*7)+(6*8)+(5*9)+(4*6)+(3*2)+(2*3)+(1*5)=183
183 % 10 = 3
So 78962-35-3 is a valid CAS Registry Number.

Synthesis of 9-epi-Mitomycin B: The First Inversion of the C-9 Stereochemistry in Mitomycin B

Kasai, Masaji,Kono, Motomichi,Shirahata, Kunikatsu

, p. 5908 - 5911 (2007/10/02)

9-epi-Mitomycin B (2b) with the same C-9 stereochemistry as mitomycin C(1) was synthesized from mitomycin B (2a) through inversion at the C-9 position. 10-O-Decarbamoylmitomycin D (8a), derived from 2a in two steps, was employed as the substrate for the epimerization.The 10-hydroxymethyl group in 8a was epimerized on treatment with diazabicycloundec-7-ene to afford 8b.Successive transformation performed on the functional groups of 8b gave the desired 2b in four steps.The stereochemistry in 2b was confirmed by conversion of 2b to the known mitomycin F (4).
