666736-72-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666736-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,7,3 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 666736-72:
(8*6)+(7*6)+(6*6)+(5*7)+(4*3)+(3*6)+(2*7)+(1*2)=207
207 % 10 = 7
So 666736-72-7 is a valid CAS Registry Number.
