219959-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219959-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219959-90:
(8*2)+(7*1)+(6*9)+(5*9)+(4*5)+(3*9)+(2*9)+(1*0)=187
187 % 10 = 7
So 219959-90-7 is a valid CAS Registry Number.
