50994-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 50994-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,9 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 50994-76:
(7*5)+(6*0)+(5*9)+(4*9)+(3*4)+(2*7)+(1*6)=148
148 % 10 = 8
So 50994-76-8 is a valid CAS Registry Number.
