71556-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71556-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,5 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71556-77:
(7*7)+(6*1)+(5*5)+(4*5)+(3*6)+(2*7)+(1*7)=139
139 % 10 = 9
So 71556-77-9 is a valid CAS Registry Number.
