220159-30-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220159-30-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220159-30:
(8*2)+(7*2)+(6*0)+(5*1)+(4*5)+(3*9)+(2*3)+(1*0)=88
88 % 10 = 8
So 220159-30-8 is a valid CAS Registry Number.
