Check Digit Verification of cas no

The CAS Registry Mumber 1421605-62-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,0 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1421605-62:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*0)+(3*5)+(2*6)+(1*2)=120
120 % 10 = 0
So 1421605-62-0 is a valid CAS Registry Number.

3-Phenacylideneoxindoles with tosylmethyl isocyanide and MeOH through C-C bond cleavage: Facile synthesis of pyrrole and 2H-pyrrolo[3,4-c]quinoline derivatives

Wang, Rong,Xu, Xiao-Ping,Meng, Hua,Wang, Shun-Yi,Ji, Shun-Jun

, p. 1761 - 1766 (2013/03/14)

A novel reaction of 3-phenacylideneoxindoles (1) with tosylmethyl isocyanide (2a) and MeOH through C-C bond cleavage has been developed. The reaction proceeded under mild conditions, providing a powerful synthetic tool for the construction of pyrrole derivatives (3) from easily accessible starting materials and synthesis of 2H-pyrrolo[3,4-c]quinolines (4) by further dehydration of 3.
