189628-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189628-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,2 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189628-77:
(8*1)+(7*8)+(6*9)+(5*6)+(4*2)+(3*8)+(2*7)+(1*7)=201
201 % 10 = 1
So 189628-77-1 is a valid CAS Registry Number.
