135423-84-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135423-84-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,4,2 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135423-84:
(8*1)+(7*3)+(6*5)+(5*4)+(4*2)+(3*3)+(2*8)+(1*4)=116
116 % 10 = 6
So 135423-84-6 is a valid CAS Registry Number.
