80172-65-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80172-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,7 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80172-65:
(7*8)+(6*0)+(5*1)+(4*7)+(3*2)+(2*6)+(1*5)=112
112 % 10 = 2
So 80172-65-2 is a valid CAS Registry Number.

LaLonde, Robert T.,Eckert, Timothy S.
, p. 2298 - 2302 (2007/10/02)
Disulfides, sulfenyl chlorides, thiosulfonates, and sulfensuccinimides were evaluated as electrophilic thiating agents for converting the enamine 6-dehydroxynupharidine to α-thiohemiaminal derivatives of the alkaloid deoxynupharidine.Sulfensuccinimides we
