111659-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111659-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 111659-90:
(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*9)+(2*9)+(1*0)=116
116 % 10 = 6
So 111659-90-6 is a valid CAS Registry Number.

, p. 1986 - 1989 (2007/10/02)
Several derivatives of diltiazem (9a-c) have been synthesized from the oxamate (6) through the carbon-carbon ring closure of the sulfur-stabilized benzylic anion and the ester carbonyl group, followed by stereoselective reduction of the C3-carb
