Check Digit Verification of cas no
The CAS Registry Mumber 38771-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,7,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38771-21:
(7*3)+(6*8)+(5*7)+(4*7)+(3*1)+(2*2)+(1*1)=140
140 % 10 = 0
So 38771-21-0 is a valid CAS Registry Number.
