753503-63-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 753503-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,5,3,5,0 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 753503-63:
(8*7)+(7*5)+(6*3)+(5*5)+(4*0)+(3*3)+(2*6)+(1*3)=158
158 % 10 = 8
So 753503-63-8 is a valid CAS Registry Number.
