148760-84-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148760-84-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,7,6 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 148760-84:
(8*1)+(7*4)+(6*8)+(5*7)+(4*6)+(3*0)+(2*8)+(1*4)=163
163 % 10 = 3
So 148760-84-3 is a valid CAS Registry Number.
