666751-06-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666751-06-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,7,5 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 666751-06:
(8*6)+(7*6)+(6*6)+(5*7)+(4*5)+(3*1)+(2*0)+(1*6)=190
190 % 10 = 0
So 666751-06-0 is a valid CAS Registry Number.
