138610-56-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138610-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,1 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138610-56:
(8*1)+(7*3)+(6*8)+(5*6)+(4*1)+(3*0)+(2*5)+(1*6)=127
127 % 10 = 7
So 138610-56-7 is a valid CAS Registry Number.

, p. 2223 - 2226 (2007/10/02)
New optically active lactams having a bicyclooctene or -octane skeleton were synthesized from D-glucuronic acid.The key step is an intramolecular cyclization of N-(p-methoxybenzyl)-1,2,3,4-tetra-O-acetyl-D-glucuronamide with simultaneous eliminatio
