502763-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 502763-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,7,6 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 502763-81:
(8*5)+(7*0)+(6*2)+(5*7)+(4*6)+(3*3)+(2*8)+(1*1)=137
137 % 10 = 7
So 502763-81-7 is a valid CAS Registry Number.

Reactivity-based one-pot synthesis of a Lewis Y carbohydrate hapten: A colon-rectal cancer antigen determinant
Mong, Kwok-Kong T.,Wong, Chi-Huey
, p. 4087 - 4090 (2007/10/03)
The stereospecific synthesis of a tumor-related carbohydrate antigenic hapten, Lewis Y, from three basic building units 1 - 3 has been achieved by a reactivity-based one-pot strategy. RRV = relative reactivity value.
