858132-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 858132-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,1,3 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 858132-53:
(8*8)+(7*5)+(6*8)+(5*1)+(4*3)+(3*2)+(2*5)+(1*3)=183
183 % 10 = 3
So 858132-53-3 is a valid CAS Registry Number.

, p. 5339 - 5341 (2011/11/14)
An efficient total synthesis of (+)-conagenin was achieved. The right fragment of conagenin, α-methylserine containing a quaternary stereocenter attached to nitrogen, was synthesized using allyl cyanate-to-isocyanate rearrangement. The left fragment, 2,4-
