1023002-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023002-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,0,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1023002-40:
(9*1)+(8*0)+(7*2)+(6*3)+(5*0)+(4*0)+(3*2)+(2*4)+(1*0)=55
55 % 10 = 5
So 1023002-40-5 is a valid CAS Registry Number.
