Check Digit Verification of cas no

The CAS Registry Mumber 37150-63-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,1,5 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 37150-63:
(7*3)+(6*7)+(5*1)+(4*5)+(3*0)+(2*6)+(1*3)=103
103 % 10 = 3
So 37150-63-3 is a valid CAS Registry Number.

Sulfonylation-induced N-to O -Acetyl migration in 2-acetamidoethanol derivatives

Yamaguchi, Takao,Hesek, Dusan,Lee, Mijoon,Oliver, Allen G.,Mobashery, Shahriar

supporting information; experimental part, p. 3515 - 3517 (2010/08/03)

The first example of sulfonylation-induced N- to O-acetyl migration of 2-acetamidoethanol derivatives is described. This type of reaction could happen with any 2-acetamidoethanol derivatives under typical sulfonylation conditions (TsCl or MsCl, pyridine) and might be a common side reaction of significance. Furthermore, the results reveal that 2-acetamidoethanol derivatives with a sterically encumbered hydroxyl group result in the migration products in high yields. The mechanism of the migration reaction is discussed.
