Check Digit Verification of cas no

The CAS Registry Mumber 1305342-71-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,5,3,4 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1305342-71:
(9*1)+(8*3)+(7*0)+(6*5)+(5*3)+(4*4)+(3*2)+(2*7)+(1*1)=115
115 % 10 = 5
So 1305342-71-5 is a valid CAS Registry Number.

Nucleophilic reactions of 9-isopropyl-2,4-dimethoxy-7,12-dimethyl-3- (phenylsulfonyl)benzo[a]heptalene with lithium dialkylamides

El Rayes, Samir,Linden, Anthony,Abou-Hadeed, Khaled,Hansen, Hans-Juergen

experimental part, p. 1195 - 1202 (2011/06/11)

Treatment of the title compounds with lithium piperidinide in THF at-5 °C leads to an exchange of the two methoxy groups by piperidino substituents (Scheme 2). On the other hand, lithium diisopropylamide (LDA) in THF at-5 °C induces the formation heptalen
