503524-88-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 503524-88-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,5,2 and 4 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 503524-88:
(8*5)+(7*0)+(6*3)+(5*5)+(4*2)+(3*4)+(2*8)+(1*8)=127
127 % 10 = 7
So 503524-88-7 is a valid CAS Registry Number.
