Check Digit Verification of cas no
The CAS Registry Mumber 1217491-63-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,4,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1217491-63:
(9*1)+(8*2)+(7*1)+(6*7)+(5*4)+(4*9)+(3*1)+(2*6)+(1*3)=148
148 % 10 = 8
So 1217491-63-8 is a valid CAS Registry Number.

, p. 1415 - 1420 (2009)
An efficient procedure for the preparation of 5- dialkylaminomethylhydantoins 3, which are easily obtained from cyclization of the corresponding urea derivatives 2 starting with β-aminoalanines 1, is described. Methylenehydantoin and the corresponding 2-t
