77336-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77336-03-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,3 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77336-03:
(7*7)+(6*7)+(5*3)+(4*3)+(3*6)+(2*0)+(1*3)=139
139 % 10 = 9
So 77336-03-9 is a valid CAS Registry Number.
