72977-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72977-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,7 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 72977-54:
(7*7)+(6*2)+(5*9)+(4*7)+(3*7)+(2*5)+(1*4)=169
169 % 10 = 9
So 72977-54-9 is a valid CAS Registry Number.
