Uses
Anti-inflammatory (topical).
Check Digit Verification of cas no
The CAS Registry Mumber 57781-15-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,8 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57781-15:
(7*5)+(6*7)+(5*7)+(4*8)+(3*1)+(2*1)+(1*5)=154
154 % 10 = 4
So 57781-15-4 is a valid CAS Registry Number.
