77093-92-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77093-92-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,9 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77093-92:
(7*7)+(6*7)+(5*0)+(4*9)+(3*3)+(2*9)+(1*2)=156
156 % 10 = 6
So 77093-92-6 is a valid CAS Registry Number.
