Check Digit Verification of cas no
The CAS Registry Mumber 638-31-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 638-31:
(5*6)+(4*3)+(3*8)+(2*3)+(1*1)=73
73 % 10 = 3
So 638-31-3 is a valid CAS Registry Number.

A highly efficient asymmetric ring-opening/cyclization/retro-Mannich reaction of cyclopropyl ketones with aryl 1,2-diamines has been realized using a chiral N,N′-dioxide/ScIIIcatalyst. Benzimidazoles containing chiral side chains were generated under mild reaction conditions in excellent outcomes (up to 99 % yield and 97 % ee). This method also provides efficient access to chiral benzimidazole-substituted amide and cycloheptene derivatives.
