123376-04-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123376-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,7 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123376-04:
(8*1)+(7*2)+(6*3)+(5*3)+(4*7)+(3*6)+(2*0)+(1*4)=105
105 % 10 = 5
So 123376-04-5 is a valid CAS Registry Number.
