161977-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161977-55-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,9,7 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 161977-55:
(8*1)+(7*6)+(6*1)+(5*9)+(4*7)+(3*7)+(2*5)+(1*5)=165
165 % 10 = 5
So 161977-55-5 is a valid CAS Registry Number.

Stereochemistry of an Allyl Cyanate-to-isocyanate Rearrangement
Ichikawa, Yoshiyasu,Tsuboi, Katsunori,Isobe, Minoru
, 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
