77286-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77286-50-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,8 and 6 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77286-50:
(7*7)+(6*7)+(5*2)+(4*8)+(3*6)+(2*5)+(1*0)=161
161 % 10 = 1
So 77286-50-1 is a valid CAS Registry Number.
