134895-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134895-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134895-89:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*5)+(2*8)+(1*9)=169
169 % 10 = 9
