102563-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102563-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,5,6 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102563-49:
(8*1)+(7*0)+(6*2)+(5*5)+(4*6)+(3*3)+(2*4)+(1*9)=95
95 % 10 = 5
So 102563-49-5 is a valid CAS Registry Number.
