128999-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128999-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,9 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128999-77:
(8*1)+(7*2)+(6*8)+(5*9)+(4*9)+(3*9)+(2*7)+(1*7)=199
199 % 10 = 9
So 128999-77-9 is a valid CAS Registry Number.
