67438-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67438-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,3 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67438-67:
(7*6)+(6*7)+(5*4)+(4*3)+(3*8)+(2*6)+(1*7)=159
159 % 10 = 9
So 67438-67-9 is a valid CAS Registry Number.
