77416-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77416-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,1 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77416-50:
(7*7)+(6*7)+(5*4)+(4*1)+(3*6)+(2*5)+(1*0)=143
143 % 10 = 3
So 77416-50-3 is a valid CAS Registry Number.
