134478-41-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134478-41-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,7 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134478-41:
(8*1)+(7*3)+(6*4)+(5*4)+(4*7)+(3*8)+(2*4)+(1*1)=134
134 % 10 = 4
So 134478-41-4 is a valid CAS Registry Number.
