766548-93-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 766548-93-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,6,5,4 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 766548-93:
(8*7)+(7*6)+(6*6)+(5*5)+(4*4)+(3*8)+(2*9)+(1*3)=220
220 % 10 = 0
So 766548-93-0 is a valid CAS Registry Number.
