Check Digit Verification of cas no

The CAS Registry Mumber 84355-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84355-17:
(7*8)+(6*4)+(5*3)+(4*5)+(3*5)+(2*1)+(1*7)=139
139 % 10 = 9
So 84355-17-9 is a valid CAS Registry Number.

FACILE SYNTHESIS OF 4-SUBSTITUTED PYRIDINES USING GRIGNARD REAGENTS

Akiba, Kin-ya,Iseki, Yuji,Wada, Makoto

, p. 3935 - 3936 (1982)

N-t-Butyldimethylsilylpyridinium triflate (2) reacted with Grignard reagents at 4-position with almost complete regioselectivity (99percent) to afford the corresponding 1,4-dihydropyridine derivatives (3), which are easily oxidized by oxygen to give 4-substituted pyridines (4: 58-70percent).
