958003-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 958003-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,8,0,0 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 958003-20:
(8*9)+(7*5)+(6*8)+(5*0)+(4*0)+(3*3)+(2*2)+(1*0)=168
168 % 10 = 8
So 958003-20-8 is a valid CAS Registry Number.
