926653-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 926653-16-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,6,6,5 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 926653-16:
(8*9)+(7*2)+(6*6)+(5*6)+(4*5)+(3*3)+(2*1)+(1*6)=189
189 % 10 = 9
So 926653-16-9 is a valid CAS Registry Number.
