76233-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76233-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,3 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76233-90:
(7*7)+(6*6)+(5*2)+(4*3)+(3*3)+(2*9)+(1*0)=134
134 % 10 = 4
So 76233-90-4 is a valid CAS Registry Number.
