874989-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874989-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,9,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 874989-77:
(8*8)+(7*7)+(6*4)+(5*9)+(4*8)+(3*9)+(2*7)+(1*7)=262
262 % 10 = 2
So 874989-77-2 is a valid CAS Registry Number.
