Check Digit Verification of cas no

The CAS Registry Mumber 910216-67-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,0,2,1 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 910216-67:
(8*9)+(7*1)+(6*0)+(5*2)+(4*1)+(3*6)+(2*6)+(1*7)=130
130 % 10 = 0
So 910216-67-0 is a valid CAS Registry Number.

, p. 719 - 746 (2020/07/13)

An efficient method for the synthesis of multi-substituted pyrroles was developed using basic cyclization of readily accessible N-Boc-N-propargylenamines. Despite the basic conditions, cleavage of the N-Boc group occurred easily. The process was rapid and afforded N-H-pyrroles with wide functional group tolerance in high yields.

Intramolecular photoaddition of vinylogous amides with allenes: A novel approach to the synthesis of pyrroles

Winkler, Jeffrey D.,Ragains, Justin R.

, p. 4031 - 4033 (2007/10/03)

Irradiation of vinylogous amide or imide 5 (R = H, alkyl, or Ac) leads to the selective formation of either crossed photoadduct 7 (R = Ac) or parallel photoadduct 8 (R = H or alkyl) as a function of the nature of the group R. The latter result leads to a
