Check Digit Verification of cas no
The CAS Registry Mumber 181629-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,6,2 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 181629-57:
(8*1)+(7*8)+(6*1)+(5*6)+(4*2)+(3*9)+(2*5)+(1*7)=152
152 % 10 = 2
So 181629-57-2 is a valid CAS Registry Number.

Semisynthesis of RPR 121056A, a major metabolite of irinotecan (CPT-11)

The semisynthesis of RPR 121056A (4), a major metabolite of irinotecan (CPT-11, 2) is reported starting from SN-38 (3) and an appropriate side-chain precursor, and using a 2-step sequence. This semisynthesis is based on the 10-O-acylation of SN-38 with the conveniently protected carbamoylchloride derivative 10 followed by cleavage of the benzylic protecting groups by hydrogenolysis. Preliminary in vitro results show that RPR 121056A displays no cytotoxicity.
