195821-53-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195821-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,8,2 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 195821-53:
(8*1)+(7*9)+(6*5)+(5*8)+(4*2)+(3*1)+(2*5)+(1*3)=165
165 % 10 = 5
So 195821-53-5 is a valid CAS Registry Number.
