667865-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 667865-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,7,8,6 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 667865-77:
(8*6)+(7*6)+(6*7)+(5*8)+(4*6)+(3*5)+(2*7)+(1*7)=232
232 % 10 = 2
So 667865-77-2 is a valid CAS Registry Number.
