55921-67-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55921-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,2 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55921-67:
(7*5)+(6*5)+(5*9)+(4*2)+(3*1)+(2*6)+(1*7)=140
140 % 10 = 0
So 55921-67-0 is a valid CAS Registry Number.
