93561-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93561-06-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,6 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93561-06:
(7*9)+(6*3)+(5*5)+(4*6)+(3*1)+(2*0)+(1*6)=139
139 % 10 = 9
So 93561-06-9 is a valid CAS Registry Number.
