Check Digit Verification of cas no

The CAS Registry Mumber 156699-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,9 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 156699-52:
(8*1)+(7*5)+(6*6)+(5*6)+(4*9)+(3*9)+(2*5)+(1*2)=184
184 % 10 = 4
So 156699-52-4 is a valid CAS Registry Number.

A NEW ROUTE TO HIGHLY SUBSTITUTED 1H-PYRROL-3(2H)-ONES

Adembri, Giorgio,Celli, Angela M.,Lampariello, Lucia R.,Scotton, Mirella,Sega, Alessandro

, p. 4023 - 4026 (1994)

Reaction of 3,4-diacetyl-3-hexen-2,5-dione, 1, with alkyl or aryl primary amines, 2a-g, led to highly substituted 1H-pyrrol-3(2H)-ones, 3a-g.The structure was established from a single crystal X-ray analysis of compound 3c.
