248948-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 248948-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,8,9,4 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 248948-63:
(8*2)+(7*4)+(6*8)+(5*9)+(4*4)+(3*8)+(2*6)+(1*3)=192
192 % 10 = 2
So 248948-63-2 is a valid CAS Registry Number.
