27748-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27748-50-1 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 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 27748-50:
(7*2)+(6*7)+(5*7)+(4*4)+(3*8)+(2*5)+(1*0)=141
141 % 10 = 1
So 27748-50-1 is a valid CAS Registry Number.
