Check Digit Verification of cas no

The CAS Registry Mumber 1375101-70-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,1,0 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1375101-70:
(9*1)+(8*3)+(7*7)+(6*5)+(5*1)+(4*0)+(3*1)+(2*7)+(1*0)=134
134 % 10 = 4
So 1375101-70-4 is a valid CAS Registry Number.

Phosphine-catalyzed [3 + 2] and [3 + 3] annulations of azomethine imines with ethyl 2-butynoate

Liu, Jun,Liu, Honglei,Na, Risong,Wang, Guiyong,Li, Zhen,Yu, Hao,Wang, Min,Zhong, Jiangchun,Guo, Hongchao

, p. 218 - 220 (2012)

The phosphine-catalyzed [3 + 2] and [3 + 3] annulation reactions of azomethine imines and ethyl 2-butynoate were developed, providing 1,2-dinitrogen-containing heterocycles tetrahydropyrazolopyrazolones and tetrahydropyrazolopyridazinones in moderate to good yields.
