927701-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 927701-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,7,7,0 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 927701-21:
(8*9)+(7*2)+(6*7)+(5*7)+(4*0)+(3*1)+(2*2)+(1*1)=171
171 % 10 = 1
So 927701-21-1 is a valid CAS Registry Number.
