94033-95-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94033-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,3 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94033-95:
(7*9)+(6*4)+(5*0)+(4*3)+(3*3)+(2*9)+(1*5)=131
131 % 10 = 1
So 94033-95-1 is a valid CAS Registry Number.
