76230-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76230-05-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,3 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76230-05:
(7*7)+(6*6)+(5*2)+(4*3)+(3*0)+(2*0)+(1*5)=112
112 % 10 = 2
So 76230-05-2 is a valid CAS Registry Number.
