1349778-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1349778-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,9,7,7 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1349778-52:
(9*1)+(8*3)+(7*4)+(6*9)+(5*7)+(4*7)+(3*8)+(2*5)+(1*2)=214
214 % 10 = 4
So 1349778-52-4 is a valid CAS Registry Number.
