1228964-33-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228964-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,9,6 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1228964-33:
(9*1)+(8*2)+(7*2)+(6*8)+(5*9)+(4*6)+(3*4)+(2*3)+(1*3)=177
177 % 10 = 7
So 1228964-33-7 is a valid CAS Registry Number.

experimental part, p. 3499 - 3507 (2010/06/17)
The stereoselective synthesis of malyngamide M (1) was accomplished in nine steps from o-cresol in 12% overall yield. The key steps involved the Wittig reaction of an α-NHBoc aryl ketone 4 for the introduction of vinyl chloride functionality, an amidation
