1023-09-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023-09-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1023-09:
(6*1)+(5*0)+(4*2)+(3*3)+(2*0)+(1*9)=32
32 % 10 = 2
So 1023-09-2 is a valid CAS Registry Number.
