27740-15-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27740-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,4 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27740-15:
(7*2)+(6*7)+(5*7)+(4*4)+(3*0)+(2*1)+(1*5)=114
114 % 10 = 4
So 27740-15-4 is a valid CAS Registry Number.
