Check Digit Verification of cas no

The CAS Registry Mumber 1372609-23-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,6,0 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1372609-23:
(9*1)+(8*3)+(7*7)+(6*2)+(5*6)+(4*0)+(3*9)+(2*2)+(1*3)=158
158 % 10 = 8
So 1372609-23-8 is a valid CAS Registry Number.

PROCESSES FOR PREPARATION OF LUBIPROSTONE

-

Paragraph 0042, (2016/11/17)

PROBLEM TO BE SOLVED: To provide new processes for preparing and purifying lubiprostone. SOLUTION: A process involves 1,4-conjugate addition of a higher order cuprate compound to a protected cyclopentenone intermediate as an important preparation step. Obtained lubiprostone is converted into a guanidine salt derivative that possesses a different melting point and solubility than lubiprostone, and thereby lubiprostone is refined. A novel synthetic intermediate is also present. COPYRIGHT: (C)2015,JPOandINPIT
