Check Digit Verification of cas no

The CAS Registry Mumber 141990-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,9,9 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 141990-23:
(8*1)+(7*4)+(6*1)+(5*9)+(4*9)+(3*0)+(2*2)+(1*3)=130
130 % 10 = 0
So 141990-23-0 is a valid CAS Registry Number.

Khan, Khalid M.,Perveen, Shahnaz,Al-Qawasmeh, Raed A.S,Shekhani, Mohammed S.,Shah, Syed T. Ali,Voelter, Wolfgang

experimental part, p. 191 - 196 (2010/04/23)

Sodium hydride (NaH) in hexamethylphosphoric triamide (HMPA) has been introduced as an economical and efficient reagent towards the creation of 1, 2- or 5, 6-enopyranosides from the corresponding halogenated or tosylated pyranosides. NaH/HMPA has several advantages compared to NaH/DMF: elimination products are produced in high yields even from sterically-hindered halides as well as tosylates. 2009 Bentham Science Publishers Ltd.
