187989-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 187989-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,9,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 187989-17:
(8*1)+(7*8)+(6*7)+(5*9)+(4*8)+(3*9)+(2*1)+(1*7)=219
219 % 10 = 9
So 187989-17-9 is a valid CAS Registry Number.
