61854-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 61854-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,8,5 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61854-12:
(7*6)+(6*1)+(5*8)+(4*5)+(3*4)+(2*1)+(1*2)=124
124 % 10 = 4
So 61854-12-4 is a valid CAS Registry Number.
