890532-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 890532-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,5,3 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 890532-99:
(8*8)+(7*9)+(6*0)+(5*5)+(4*3)+(3*2)+(2*9)+(1*9)=197
197 % 10 = 7
So 890532-99-7 is a valid CAS Registry Number.
