205052-95-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205052-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,0,5 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 205052-95:
(8*2)+(7*0)+(6*5)+(5*0)+(4*5)+(3*2)+(2*9)+(1*5)=95
95 % 10 = 5
So 205052-95-5 is a valid CAS Registry Number.
