287110-54-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 287110-54-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,1,1 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 287110-54:
(8*2)+(7*8)+(6*7)+(5*1)+(4*1)+(3*0)+(2*5)+(1*4)=137
137 % 10 = 7
So 287110-54-7 is a valid CAS Registry Number.
