139978-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139978-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,7 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139978-95:
(8*1)+(7*3)+(6*9)+(5*9)+(4*7)+(3*8)+(2*9)+(1*5)=203
203 % 10 = 3
So 139978-95-3 is a valid CAS Registry Number.
