112978-74-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112978-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,9,7 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112978-74:
(8*1)+(7*1)+(6*2)+(5*9)+(4*7)+(3*8)+(2*7)+(1*4)=142
142 % 10 = 2
So 112978-74-2 is a valid CAS Registry Number.
