Check Digit Verification of cas no

The CAS Registry Mumber 1262801-63-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,0 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1262801-63:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*0)+(3*1)+(2*6)+(1*3)=137
137 % 10 = 7
So 1262801-63-7 is a valid CAS Registry Number.

Enantioselective synthesis of densely functionalized pyranochromenes via an unpredictable cascade Michael-oxa-Michael-tautomerization sequence

Ren, Qiao,Gao, Yaojun,Wang, Jian

supporting information; experimental part, p. 13594 - 13598 (2011/02/26)

A surprising example of enantioselective cascade Michael-oxa-Michael- tautomerization reactions of malononitrile and benzylidenechromanones has been developed. In this case, malononitrile functions as both nucleophile and electrophile. Meanwhile, a simple
