106657-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106657-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,6,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 106657-16:
(8*1)+(7*0)+(6*6)+(5*6)+(4*5)+(3*7)+(2*1)+(1*6)=123
123 % 10 = 3
So 106657-16-3 is a valid CAS Registry Number.
