27805-30-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27805-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,8,0 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27805-30:
(7*2)+(6*7)+(5*8)+(4*0)+(3*5)+(2*3)+(1*0)=117
117 % 10 = 7
So 27805-30-7 is a valid CAS Registry Number.
