Check Digit Verification of cas no

The CAS Registry Mumber 187083-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,0,8 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 187083-38:
(8*1)+(7*8)+(6*7)+(5*0)+(4*8)+(3*3)+(2*3)+(1*8)=161
161 % 10 = 1
So 187083-38-1 is a valid CAS Registry Number.

Synthesis of DNA-interactive pyrrolo[2,1-c][1,4]benzodiazepines by employing polymer-supported reagents: Preparation of DC-81

Kamal, Ahmed,Reddy, K. Laxma,Devaiah,Shankaraiah

, p. 2533 - 2536 (2004)

Polymer-supported reagents have been utilized for the generation of combinatorial library of substituted pyrrolo[2,1-c][1,4]benzodiazepine derivatives that provides a clean and efficient preparation and does not require conventional purification techniques like chromatography. This methodology involves intra molecular aza-Wittig reaction and has been extended for the synthesis of the natural product DC-81 in good overall yields.
