128763-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128763-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,6 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128763-77:
(8*1)+(7*2)+(6*8)+(5*7)+(4*6)+(3*3)+(2*7)+(1*7)=159
159 % 10 = 9
So 128763-77-9 is a valid CAS Registry Number.
