Check Digit Verification of cas no

The CAS Registry Mumber 203728-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,7,2 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203728-08:
(8*2)+(7*0)+(6*3)+(5*7)+(4*2)+(3*8)+(2*0)+(1*8)=109
109 % 10 = 9
So 203728-08-9 is a valid CAS Registry Number.

, p. 4175 - 4178 (2010)

Chiral N,N′-dioxide-Ytterbium(III) complexes promoted the asymmetric addition of diethyl phosphate to aldehydes, giving the corresponding products with good yields and enantioselectivities. The addition of pyridine favored both reactivity and enantioselec
