71519-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71519-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71519-98:
(7*7)+(6*1)+(5*5)+(4*1)+(3*9)+(2*9)+(1*8)=137
137 % 10 = 7
So 71519-98-7 is a valid CAS Registry Number.
