Check Digit Verification of cas no

The CAS Registry Mumber 637331-17-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,3,3 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 637331-17:
(8*6)+(7*3)+(6*7)+(5*3)+(4*3)+(3*1)+(2*1)+(1*7)=150
150 % 10 = 0
So 637331-17-0 is a valid CAS Registry Number.

Diels-Alder reaction of 2-nitro glycals: A new route to the synthesis of benzopyrans

Pachamuthu, Kandasamy,Schmidt, Richard R.

, p. 1355 - 1357 (2003)

Synthesis of different benzopyrans was achieved by Diels-Alder reaction of 2-nitro glycals with Danishefky's diene, hydrolysis of the enol ether moiety, and subsequent elimination of the nitro and methoxy group.
