7685-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7685-70-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7685-70:
(6*7)+(5*6)+(4*8)+(3*5)+(2*7)+(1*0)=133
133 % 10 = 3
So 7685-70-3 is a valid CAS Registry Number.
