134197-95-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134197-95-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,1,9 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134197-95:
(8*1)+(7*3)+(6*4)+(5*1)+(4*9)+(3*7)+(2*9)+(1*5)=138
138 % 10 = 8
So 134197-95-8 is a valid CAS Registry Number.
