199061-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199061-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,0,6 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 199061-52:
(8*1)+(7*9)+(6*9)+(5*0)+(4*6)+(3*1)+(2*5)+(1*2)=164
164 % 10 = 4
So 199061-52-4 is a valid CAS Registry Number.
