76123-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76123-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,2 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76123-31:
(7*7)+(6*6)+(5*1)+(4*2)+(3*3)+(2*3)+(1*1)=114
114 % 10 = 4
So 76123-31-4 is a valid CAS Registry Number.
