877807-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 877807-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,8,0 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 877807-48:
(8*8)+(7*7)+(6*7)+(5*8)+(4*0)+(3*7)+(2*4)+(1*8)=232
232 % 10 = 2
So 877807-48-2 is a valid CAS Registry Number.
