77435-40-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77435-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,3 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77435-40:
(7*7)+(6*7)+(5*4)+(4*3)+(3*5)+(2*4)+(1*0)=146
146 % 10 = 6
So 77435-40-6 is a valid CAS Registry Number.
