102520-04-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102520-04-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,5,2 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 102520-04:
(8*1)+(7*0)+(6*2)+(5*5)+(4*2)+(3*0)+(2*0)+(1*4)=57
57 % 10 = 7
So 102520-04-7 is a valid CAS Registry Number.
