71667-25-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71667-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,6 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 71667-25:
(7*7)+(6*1)+(5*6)+(4*6)+(3*7)+(2*2)+(1*5)=139
139 % 10 = 9
So 71667-25-9 is a valid CAS Registry Number.
