16780-62-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 16780-62-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,8 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16780-62:
(7*1)+(6*6)+(5*7)+(4*8)+(3*0)+(2*6)+(1*2)=124
124 % 10 = 4
So 16780-62-4 is a valid CAS Registry Number.
