Check Digit Verification of cas no
The CAS Registry Mumber 130836-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,8,3 and 6 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130836-56:
(8*1)+(7*3)+(6*0)+(5*8)+(4*3)+(3*6)+(2*5)+(1*6)=115
115 % 10 = 5
So 130836-56-5 is a valid CAS Registry Number.

New Protocols for the Synthesis of Substituted 4-O-Methyl Tetramates
Jones, Raymond C. F.,Patience, Jacqueline M.
, p. 2350 - 2351 (2007/10/02)
The deprotonation behaviour of 4-methoxypyrrol-2(5H)-ones (4-O-methyl tetramates) is defined and exploited to provide methods for the synthesis of methyl tetramates variously substituted at N-1, C-5, and C-3.
