Check Digit Verification of cas no

The CAS Registry Mumber 1309440-27-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,4,4 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1309440-27:
(9*1)+(8*3)+(7*0)+(6*9)+(5*4)+(4*4)+(3*0)+(2*2)+(1*7)=134
134 % 10 = 4
So 1309440-27-4 is a valid CAS Registry Number.

supporting information; experimental part, p. 8428 - 8431 (2011/07/29)

The diastereoselectively switchable enantioselective trapping of protic carbamate ammonium ylides with imines is reported. The intriguing Rh 2(OAc)4 and chiral Bronsted acid cocatalyzed three-component Mannich-type reaction of a diazo compound, a carbamate, and an imine provides rapid and efficient access to both syn- and anti-α- substituted α,β-diamino acid derivatives with a high level control of chemo-, diastereo-, and enantioselectivity.
