Check Digit Verification of cas no
The CAS Registry Mumber 103312-62-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,1 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 103312-62:
(8*1)+(7*0)+(6*3)+(5*3)+(4*1)+(3*2)+(2*6)+(1*2)=65
65 % 10 = 5
So 103312-62-5 is a valid CAS Registry Number.

Synthesis of lansoprazole and rabeprazole using common intermediates is devised. The common intermediates, 2-[(4-nitro-3-methylpyridin-2-yl) methanesulfanyl]-1H-benzoimidazole and 2-[(4-chloro-3-methyl-pyridin-2-yl) methanesulfanyl]-1H-benzoimidazole, were prepared in several ways.
