1387563-63-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1387563-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,7,5,6 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1387563-63:
(9*1)+(8*3)+(7*8)+(6*7)+(5*5)+(4*6)+(3*3)+(2*6)+(1*3)=204
204 % 10 = 4
So 1387563-63-4 is a valid CAS Registry Number.
