25784-62-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25784-62-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,8 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25784-62:
(7*2)+(6*5)+(5*7)+(4*8)+(3*4)+(2*6)+(1*2)=137
137 % 10 = 7
So 25784-62-7 is a valid CAS Registry Number.
