378238-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 378238-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,8,2,3 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 378238-90:
(8*3)+(7*7)+(6*8)+(5*2)+(4*3)+(3*8)+(2*9)+(1*0)=185
185 % 10 = 5
So 378238-90-5 is a valid CAS Registry Number.
