189622-80-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189622-80-8 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 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 189622-80:
(8*1)+(7*8)+(6*9)+(5*6)+(4*2)+(3*2)+(2*8)+(1*0)=178
178 % 10 = 8
So 189622-80-8 is a valid CAS Registry Number.
