681264-16-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 681264-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,2,6 and 4 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 681264-16:
(8*6)+(7*8)+(6*1)+(5*2)+(4*6)+(3*4)+(2*1)+(1*6)=164
164 % 10 = 4
So 681264-16-4 is a valid CAS Registry Number.
