205052-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 205052-97-7 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 7 respectively.
Calculate Digit Verification of CAS Registry Number 205052-97:
(8*2)+(7*0)+(6*5)+(5*0)+(4*5)+(3*2)+(2*9)+(1*7)=97
97 % 10 = 7
So 205052-97-7 is a valid CAS Registry Number.
