77995-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77995-36-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,9 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77995-36:
(7*7)+(6*7)+(5*9)+(4*9)+(3*5)+(2*3)+(1*6)=199
199 % 10 = 9
So 77995-36-9 is a valid CAS Registry Number.
