134920-18-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134920-18-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,2 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134920-18:
(8*1)+(7*3)+(6*4)+(5*9)+(4*2)+(3*0)+(2*1)+(1*8)=116
116 % 10 = 6
So 134920-18-6 is a valid CAS Registry Number.
