1027990-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027990-71-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,9 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1027990-71:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*9)+(3*0)+(2*7)+(1*1)=161
161 % 10 = 1
So 1027990-71-1 is a valid CAS Registry Number.

, p. 2791 - 2796 (2007/10/02)
The stereochemistry of an allyl cyanate-to-isocyanate rearrangement has been investigated by employing a chiral allyl carbamate.The rearrangement has been found to be stereospecific and the chirality of an allyl cyanate is transformed into that of an ally
