7661-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7661-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,6 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7661-13:
(6*7)+(5*6)+(4*6)+(3*1)+(2*1)+(1*3)=104
104 % 10 = 4
So 7661-13-4 is a valid CAS Registry Number.
