645394-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 645394-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,5,3,9 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 645394-63:
(8*6)+(7*4)+(6*5)+(5*3)+(4*9)+(3*4)+(2*6)+(1*3)=184
184 % 10 = 4
So 645394-63-4 is a valid CAS Registry Number.
