7658-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7658-30-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,5 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.Calculate Digit Verification of CAS Registry Number 7658-30:
(6*7)+(5*6)+(4*5)+(3*8)+(2*3)+(1*0)=122
122 % 10 = 2
So 7658-30-2 is a valid CAS Registry Number.
