195141-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 195141-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,5,1,4 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 195141-52:
(8*1)+(7*9)+(6*5)+(5*1)+(4*4)+(3*1)+(2*5)+(1*2)=137
137 % 10 = 7
So 195141-52-7 is a valid CAS Registry Number.
