Check Digit Verification of cas no

The CAS Registry Mumber 1203948-45-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,9,4 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1203948-45:
(9*1)+(8*2)+(7*0)+(6*3)+(5*9)+(4*4)+(3*8)+(2*4)+(1*5)=141
141 % 10 = 1
So 1203948-45-1 is a valid CAS Registry Number.

Garcia, Lidia,Pla-Quintana, Anna,Roglans, Anna

experimental part, p. 5020 - 5027 (2010/02/15)

Non-proteinogenic phenylalanine derivatives were efficiently prepared by Rh(I)-catalyzed [2+2+2] cycloaddition reactions between enantiopure and racemic propargylglycine amino acids, with different protective groups, and diynes. Diverse substituents, incl
