105621-27-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105621-27-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,6,2 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 105621-27:
(8*1)+(7*0)+(6*5)+(5*6)+(4*2)+(3*1)+(2*2)+(1*7)=90
90 % 10 = 0
So 105621-27-0 is a valid CAS Registry Number.
