84235-67-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84235-67-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,3 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84235-67:
(7*8)+(6*4)+(5*2)+(4*3)+(3*5)+(2*6)+(1*7)=136
136 % 10 = 6
So 84235-67-6 is a valid CAS Registry Number.
