189630-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189630-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,6,3 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189630-44:
(8*1)+(7*8)+(6*9)+(5*6)+(4*3)+(3*0)+(2*4)+(1*4)=172
172 % 10 = 2
So 189630-44-2 is a valid CAS Registry Number.
